I've just upgraded to a GF4 4200 and UT 2003 crashes randomly if I have a second monitor enabled. Flying AH offline seems fine, but can others confirm that they don't have problems with multiple monitors?
XP SP1, 1GB, ABit VP6, 2x P3-1000, SB Live, 3c905, EIDE, yada.
Incidentally, it would be really useful to be able to put the radar and message boxes on the second monitor.
