I'm Having a serious problem with Photoshop CS & CS2 and XP 64 bit on Two Computers. Both are AMD 3800x2's with 2gb ram, ATI 9550 video cards.They seem to run most other applications fine (Office 2003, Nero 6.0.16, Nero Vision 3.0, DVD shrink, etc). Both versions of Photoshop Install, open, and work fine until You close Photoshop. Upon closing I get a Blue Screen and the error "Kernel_APC_Pending During Exit". It's defenitly a problem with XP 64 bit because both computers are dual boot and there is no problem in 32 bit XP Pro. Anyone have any idea's that may help?
