I am amazed to see for myself that tutorials built with the Chime template I released in 1998, such as Hemoglobin at MolviZ.Org, work perfectly in the current Gecko family of browsers, without modification (except for font sizes and font-size controls). These are Netscape 7.2, Mozilla and Firefox. In fact, all the tutorials in the big illustrated table at the top of MolviZ.Org work fine, including ones with unusual structures such as DNA, lipid bilayers, communication between IR spectral peaks and molecular vibrations (jcamp), and animations saved from PE. In contrast, Internet Explorer will not work with these unless they are specifically adapted, which most have not been. I have not yet documented the compatibility of these many tutorials with Netscape 7, Mozilla, and Firefox. For those whose IT support groups refuse to install Netscape 4.8 on campus computer lab systems, Netscape 7 provides a workable alternative for legacy Chime-based tutorials, scores of which are indexed at http://molvisindex.org. You would just need to get the IT group to install the Chime plugin manually, which is a trivial process of copying a single file http://www.umass.edu/microbio/chime/beta/pe_gecko/protexpl/chiminst.htm -Eric ---- Eric Martz, Professor Emeritus, Dept Microbiology University of Massachusetts, Amherst MA US http://www.umass.edu/molvis/martz
