Indoor map bugged

when I go indoors, like dungeons, missions, shops, my map shows only big white squares instead small dots for people, maschines, monster. The map works outside as normal as before. Only inside seem to be bugged.
I use a Voodoo 3 2000 video card in a windows 98 system.
The bug appeared after 14.7.1 patch, Notum Wars (14.7.0) isnt installed.

The prob is with the voodo and the new patch. Had the same prob, changed card to a GEforce and fixed it right up. Spoke to a GM about it and sent some screen shots, was told they are working on a fix.
