Alright so I've been completely perplexed here. I run Windows Vista on~

AMD Athlon(tm) X2 Dual Core Processor BE-2350 (2 CPUs), ~2.1GHz
ATI Radeon X1250
2GB RAM

and I work as a 3D Modeler. I use alot of programs such as Torque Game
Builder and 3Ds MAX. Now I've disabled UAC and Windows Defender and the
problem still persists.
When I'm running say 3Ds MAX (happens with most of my developer apps)
and I go to save, or open a file, certain folders will cause the entire
application to crash; and this is WHILE saving.. so you can see my urgency.
Can anyone offer a solution?
Thanks
