Hi Mark, We've seen this problem too, and think it's a conflict between certain graphics cards and MapInfo Pro's internal map redraw optimization routine. A work-around is to disable Pro's optimization, and that's done in the registry by setting the key (adding it, if it's not there) "HKEY_LOCAL_MACHINE/Software/MapInfo/MapInfo/Common/OffScreenBitmap" to 0 (maybe string "0"). And restart Pro. The redraw will be slower, but you won't have any fragmentation problems. I don't know why it happens on some machines. Maybe the graphic card's too fast, or maybe it's not 100% complaint to specs. If anyone's got an idea as to the core of the problem, I'd be delighted to know too.

I assume it is some incompatibility between MapInfo and the video card - we have had three different machines/cards over the eyars and the problem still pops up now and then. I haven't been able to work out what the problem is or what triggers it, but it does seem to happen more when you have lots of layers in view. We are still using 4.1.2 so I don't know if this is a problem with later versions. If you find how to eliminate it, please let me know.
