Dear Paul and Nat: I now have Firefox with Chime 2.6 SP6 installed on my Windows XP Pro SP1 Dell Notebook computer. Firefox completes the Chime speed test successfully for PE 2.7 both on-line and downloaded, displaying the QuickView 1D66 on both cases. So I am not seeing the stall you saw during the Chime speed tests. Nor am I having any problems with Chime SP6, in contrast to Paul Pillot. If others have tried PE 2.7 in Firefox (or any other Gecko browser) in a Windows XP (SP1 or SP2) computer, I'd appreciate hearing whether there were any problems. -Eric At 1/29/2005, you wrote: >I encountered a problem in running chime 2.6 SP6 in firefox with Win XP. >The replacement of chime 2.6SP6 by a previous version as 2.6 SP4 fix that. /* - - - - - - - - - - - - - - - - - - - - - - - - - - - Protein Explorer - 3D Visualization: http://proteinexplorer.org Workshops: http://www.umass.edu/molvis/workshop Biochem Structure Tutorials http://MolviZ.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://molvis.sdsc.edu/atlas/atlas.htm PDB Lite Macromolecule Finder: http://pdblite.org Molecular Visualization EMail List (molvis-list): http://bioinformatics.org/mailman/listinfo/molvis-list Eric Martz, Professor Emeritus, Dept Microbiology U Mass, Amherst MA US 413-545-2325/FAX 413-545-2532 http://www.umass.edu/molvis/martz - - - - - - - - - - - - - - - - - - - - - - - - - - - */
