My Windows Vista & XP installs have a odd issue with DirectX
On Vista, Programs WinSAT & Dreamscene keep crashing due to dll d3d9.dll
On Windows XP the only issue I've had is with camtasia studio but i can turn off DirectX accelerations and it works fine
I've tried swapping out the ATI card that came with my computer for the NVIDIA one but still same error
On Windows 7 & up this doesn't happen
