This is the official solution for allow plugins (in this case Quicktime) to again be played on
MS IE 5.5 SP2 and IE6 XP. One presumes a similar solution will be required
for Chime and other Chemical plugins. The example below suggests that
an ActiveX control is downloaded from the Internet. I presume a stand alone
solution suitable for eg CDROMs will also materialise.
Note how the onus is on the content developer to CHANGE their HTML
page to make it work. I wonder how many will.

>Windows Internet Explorer 5.5 SP2 and 6.0 with QuickTime
>IMPORTANT INFORMATION FOR WEB DEVELOPERS & WEBMASTERS
>
>Microsoft Internet Explorer for Windows, versions 5.5 SP2 and 6.0
>(soon to be released) no longer support Netscape-style plug-ins,
>such as the plug-in installed as part of QuickTime 5.0.2 and earlier
>versions. Consequently, Windows customers using these versions of
>Explorer who visit your site may be unable to view QuickTime content
>in the browser. To mitigate this problem and to ensure a positive
>experience for your Web site visitors, you should add to your site
>the HTML code that makes available the new ActiveX control for
>QuickTime, as described below.
>
>NOTE: THIS ISSUE AFFECTS ONLY USERS OF INTERNET EXPLORER ON WINDOWS.
>
>BACKGROUND
>QuickTime uses a plug-in mechanism to display movies from your Web
>page in the user's browser. Before, you would use an EMBED element
>alone to display QuickTime content within the browser, much like in
>the example below:
>
><EMBED src="sample.mov" width="160" height="144" autoplay="true"
>CONTROLLER="false"
>PLUGINSPAGE="http://www.apple.com/quicktime/download/"> </EMBED>
>
>For this mechanism to work, the user must have the QuickTime plug-in
>installed on his or her system. If the appropriate QuickTime plug-in
>is not installed, when your HTML page with QuickTime content is
>loaded into the user's browser, the movie is not visible. Instead,
>the browser replaces it with a "broken plug-in icon" and attempts to
>assist the user in obtaining the required software. An unfortunate
>side effect of this approach is that the user is directed away from
>your site and is distracted by the installation process.
>
>THE ISSUE
>Until recently, the plug-in installed as part of QuickTime worked
>for both Netscape browsers and Microsoft Internet Explorer on both
>Windows and Mac OS. Now Windows users who try to play a QuickTime
>movie in Internet Explorer version 5.5 SP2 or later will encounter
>the "broken plug-in icon" until they install the new QuickTime
>ActiveX control from Apple in addition to the QuickTime plug-in.
>Users of other browsers on either Windows or Mac OS are
>unaffected--they can continue to use the plug-in installed with
>QuickTime and do not need to get the new QuickTime ActiveX control.
>
>Once users have the new ActiveX control installed, they are also
>unaffected; they can also view existing pages.
>
>THE SOLUTION
>When authoring web pages, you can easily prevent this problem by
>authoring your HTML to check that the required ActiveX control is
>installed wherever you have QuickTime content embedded. This HTML
>change will result in web pages compatible with Netscape and
>Internet Explorer browsers on both Mac and Windows systems (see
>below for more information).
>
>The required code consists of an HTML OBJECT element with an
>enclosed EMBED element as in the following example:
>
><OBJECT CLASSID="clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B"
>width="160" height="144"
>CODEBASE="http://www.apple.com/qtactivex/qtplugin.cab">
><param name="src" value="sample.mov">
><param name="autoplay" value="true">
><param name="controller" value="false">
><embed src="sample.mov" width="160" height="144" autoplay="true"
>CONTROLLER="false"
>PLUGINSPAGE="http://www.apple.com/quicktime/download/"></EMBED>
></OBJECT>
>
>CLASSID must always equal:
>clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B
>CODEBASE must always equal:
>http://www.apple.com/qtactivex/qtplugin.cab
>PLUGINSPAGE must always equal:
>http://www.apple.com/quicktime/download/
>
>The other attributes should be customized to your web page. You need
>to substitute "sample.mov" (in both SRC attribute elements) with the
>URL of the actual movie to be played. You should also change the
>HEIGHT and WIDTH parameters to match the height and width of the
>movie (in pixels).
>
>If you already have EMBED elements for the QuickTime plug-in on the
>relevant pages, you need to enclose each of them in an OBJECT
>element with CLASSID and CODEBASE parameter values as shown above
>and with SRC and other parameter values to match those in your
>existing EMBED element. The OBJECT element can use any EMBED
>attributes QuickTime understands. Visit
>http://www.apple.com/quicktime/authoring/embed.html for more
>information.
>
>For existing web pages, it may be sufficient to add such an OBJECT
>element to the "front door" page of your site. Once the OBJECT
>element on the "front door" page has caused the user to install the
>ActiveX control, all subsequent pages with the original EMBED
>elements will work properly. In cases where you cannot be certain
>that the "front door" page is always visited, then all your pages
>should be revised to use these OBJECT elements.
>
>HOW IT WORKS
>The OBJECT element is used by Internet Explorer on Windows
>9x/NT/2000/XP platforms and by other browsers that support the
>QuickTime ActiveX control. The enclosed EMBED element is used by
>Netscape browsers, Internet Explorer for the Mac, and other browsers
>that support the "Netscape style" QuickTime plug-in. Browsers that
>understand the OBJECT element ignore the EMBED element; those that
>don't understand the OBJECT element use the EMBED element.
>
>Within the OBJECT element, the CLASSID parameter uniquely identifies
>which ActiveX control to use. A CLASSID parameter with the value
>"clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B" tells Internet Explorer
>to use the QuickTime ActiveX control. (You must use exactly this
>value; it is the only value that identifies the QuickTime ActiveX
>control). If the user does not already have the ActiveX control
>installed on his or her system, the CODEBASE parameter tells the
>browser where to find it for downloading. Internet Explorer will
>automatically offer to download and install the ActiveX control for
>the user, after which the movie can be played without restarting the
>browser, or, if QuickTime is not already installed, will prompt the
>user to download and install QuickTime. You must always use
>"http://www.apple.com/qtactivex/qtplugin.cab" for the CODEBASE URL.
>This URL will always have the latest version of the QuickTime
>ActiveX control.
>Because a browser will use either the OBJECT element or the EMBED
>element, but not both, most of the element attributes must be
>included in each. Note that in the example above the EMBED element
>has autoplay="true" and the OBJECT element has <param
>name="autoplay" value="true">, so the movie will begin to play
>automatically whether it is loaded with the QuickTime ActiveX
>control or the QuickTime plug-in. The only attributes that should
>not be duplicated are CLASSID, CODEBASE, and PLUGINSPAGE. CLASSID
>and CODEBASE are specific to the OBJECT element. PLUGINSPAGE is
>specific to the EMBED element.
>
>Although Windows Internet Explorer 5.5 SP2 and 6.0 will no longer
>use the QuickTime plug-in, once the QuickTime ActiveX control has
>been installed on a user's system, these versions of Internet
>Explorer will use the installed ActiveX control to satisfy a
>properly coded EMBED element.

Hi there,
Does anyone know of a good source of information concerning the
structural characteristics of CuSO4.5H2O (especially when linked to
Thermal Gravimetric Analysis).
