DOES ANYONE HAVE ANY INSIGHTS ABOUT HOW TO GET CHIME'S MESSAGECALLBACK TO WORK IN MICROSOFT INTERNET EXPLORER VERSION 7? (Details follow.) Internet Explorer version 7 is now available, and recommended by Microsoft. It replaces version 6 that has been recommended for several years. You are supposed to be able to uninstall it (presumably going back to IE6) but I haven't tried this. My preliminary tests with Chime in IE7 (done in Windows XP SP2) indicate: 1. The MDL Chime 2.6 SP6 installer successfully installs Chime for IE7 using the Windows Registry. (This avoids needing to manually copy npchime.dll, required for installation for Firefox and other Gecko browsers.) (The installation test was done with IE7 installed in its default location.) 2. Chime sites that do not use messageCallback (and that are compatible with IE6) work fine in IE7. 3. Chime sites that use messageCallback (and that are compatible with IE6) do not work properly in IE7. Each messageCallback generates an alert "The data that the plugin requested, did not download successfully". Chime loads and displays the molecule, and Chime's menu is available (after left-clicking on Chime, a new requirement in IE7) and works. I tried playing with IE7's settings a bit but did not find one that solved the messageCallback problem. Since Protein Explorer uses messageCallback to test whether Chime is installed, it fails to start. Also, it uses messageCallback very extensively, so even if it did start, it will not work. Therefore, people who plan to use Protein Explorer should plan to use Firefox if they plan to upgrade to IE7. Firefox supports all of PE's capabilities; IE6 does not; IE7 will not run PE at all. /* - - - - - - - - - - - - - - - - - - - - - - - - - - - Eric Martz, Professor Emeritus, Dept Microbiology U Mass, Amherst -- http://www.umass.edu/molvis/martz Biochem 3D Education Resources http://MolviZ.org See 3D Molecules, Install Nothing! - http://firstglance.jmol.org Protein Explorer - 3D Visualization: http://proteinexplorer.org Workshops: http://workshops.proteinexplorer.org World Index of Molecular Visualization Resources: http://molvisindex.org ConSurf - Find Conserved Patches in Proteins: http://consurf.tau.ac.il Atlas of Macromolecules: http://atlas.proteinexplorer.org PDB Lite Macromolecule Finder: http://pdblite.org Molecular Visualization EMail List (molvis-list): http://bioinformatics.org/mailman/listinfo/molvis-list - - - - - - - - - - - - - - - - - - - - - - - - - - - */
