Does anyone know where I can find mouse drivers that work under SuperVGA modes? I have one from Logitech that works in VGA mode, but once I switch to 1024x768 the mouse pointer disappears. Michael

The problem is that no two VGA manufacturers use the same method of 'page swapping', which is necessary for most of the enhanced VGA modes. The mouse drivers need to know how to do this to draw in (and erase) the mouse cursor, one alternative is to come out with many different mouse drivers (yuck!). Another is to punt and rely on the applications themselves (or the graphics library they use) to handle it for them. I know, I have to do this very thing. I wish there was a way to tell the Microsoft Mouse interface that 'Here is the routine to call to update the mouse position' or some such. That would have made the job so much easier! -- Bill Marsh, Naval Ocean Systems Center, San Diego, CA {arpa,mil}net: bmarsh@cod.nosc.mil uucp: {ihnp4,akgua,decvax,dcdwest,ucbvax}!sdcsvax!nosc!bmarsh "If everything seems to be coming your way, you're probably in the wrong lane."
