I have a Dell M90 with Nvidia 3500M video card. I have tried every driver from Nvidia and SW "tested and certified".....those two terms I use loosely of course. While running dual monitors it works fine for awhile. Open some parts....closes some parts.....open assemblies....ect...I'm working right!? Then I go to and close the SW window down, open it back up when needed and my wallpaper bleeds though. If I try to scale the window myself it looks like I have a million windows open. The opening screen of SW 2009 also looks good when I first open the program. After using SW for a while, that home screen now looks black. Running SW 2007 for almost 2 years I did not have any issues with the Dell M90, Nvidia card, and dual monitors. Just today we tried replacing the video card with a new one.....some stuff. What is going on here!
