White screen bug when selecting units in RV

[BluntF]

Also I have a gts 450 on win 7 64 bit. The problem I have with all HPS games is clicking hexes gives graphical bugs like units disappearing, unit images not showing up etc etc.

I have the latest nvidia beta drivers off their site, everything is fine, however if I have windows AERO desktop activated this issue doesnt go away. Once I go to Windows Classic Theme, its all good.

Very odd
