With the final release of Chime 2 for Windows and Mac users, I have noted one syndrome for Mac users (I have not tested under Windows) that might cause unexpected behaviour using Netscape. The manifestation is that Netscape appears not to recognise PDB files read from a LOCAL disk as having a corresponding plug-in with which to view them (it should of course be Chime). This is because Chime now supports three different extensions for PDB files (pdb, emb, embl) rather than just one previously. These extensions are not automatically written into the Netscape preferences file. To force them to enter, one should manually delete the chemical/x-pdb file from the Prefs/Applications section, quit Netscape (to force a new Netscape prefs to be written) and then restart Netscape and quit once more. Now, the prefs file will correctly include the new extensions, and now the browser will recognise PDB files from local hard disk. Dr Henry Rzepa, Dept.
