Pointer Cam not working on 6.3

I’m using 6.3 on X86. I use the pointer cam with PhAB to line things up
visually to the pixel. In 6.3, pointer cam is not working. When it is
enabled it displays that first frame, but as you move the cursor, the image
doesn’t update.

My video card is:
Class = Display (VGA)
Vendor ID = 1002h, ATI Technologies
Device ID = 4750h, Rage 3D Pro PCI Graphics Accelerator
