Crazy issue - All W2K network with all O2K installed, some but not all users, cannot open jpg files (double-click via file associations) with 'normal' MS Photo-editor app. These users can open the jpgs on machines that have another app like corel or photoshop. When 'open-with...' is set to MSPE, still get same error: "No file format info can be found in the Registry." This doesn't seem to be correct. Perhaps a group policy issue... again not all users have this problem, only some on all machines.
Again, this is an file-type association issue and not an 'opening' issue, so please not comments about how to open jpgs in IE.
