Hi, I have a Dell Precision Workstation 670 running on XP-64bit, 2.0GB Ram with an NVIDIA Quadro FX 3400/4400 512MB video card, driver version 5.40.02.38.10 , with dell 19' dual LCD monitors. I run 3D software like 3d studio 7.0 Autodesk, Adobe After Effects, Photoshop, Maya Alias Wavefront and more multimedia and compositing programs. The problem that I have is that every time that I am using the software maximize on both monitors for a while and then I minimize to go to the desktop the computer will freeze for at least 25 seconds or more, the machine will do this also every time I jump from one aplication to another aplications. I don't get any errors, the machine is not overclock. It looks that Windows XP64 does not handled very well the 2 monitors !! I checked my virtual memory and is fine I also checked on the video card settings and everthing looks fine. ...any clue? Thanks xmarcelo
