I have hitherto only tried the Chime plug-in for viewing pdb files in the regular "HTML" Netscape browser window. Today I decided to see what it would do in the Mail window. 1. Firstly, if one attaches a PDB file as "source" from the send mail feature, it correctly attaches the chemical/x-pdb MIME header. 2. Using Netscape 2.02 (Mac), one can read this file, and it comes over as an attachment with the MIME type correct. I was rather hoping against hope that the molecule itself would be in-lined into the mail message body. But although it makes an attempt to read it (the pdb is 191K in size, and it takes about 3 seconds to read this in) no molecule appears. Clicking on the "Attachment" hyperlink produces a "loading plug-in" message, but no molecule appears in the mail windows, although it does go black in preparation. The usual Chime pull down menus only partially appear. If exactly the same attached pdb file is opened instead in the usual browser window, a fully working Chimed molecule appears 3. Using Netscape 3.0b5 produces different behaviour, on exactly the same mailbox entries. Rather than labelling the attachment as such, the file name appears with a random name apparently associated with an earlier e-mail attachment. Clicking on the hyperlink now does produce a Chimed molecule, but this appears in the regular browser window rather than the Mail Window. The purpose of this message is (a) to find out whether all this behaviour is reproducible on other peoples systems, and using other versions of Netscape browsers. (b) To bring to peoples attention that "active" molecules can be sent with e-mail messages and viewed with Chime as a plug-in. Shame that Eudora does not support Netscape plug-ins!
