Hi there. Have been using dos apps from floppy images successfully for some time. But this one (similar) app will crash when ran from a mounted image, while it will run perfectly from a mounted physical floppy drive. What makes one work while the other will not? Same thing on different PCs (xp, 2k) with different hardware. Also tried different image formats. Must be a dos setting I guess, but apparently not the files and buffers settings. Any help welcome. Thanks!
