Hey Doug. I had a similar problem with my PD6 a while ago. It ran great on XP, but would quit responding when I tried it on Vista. Like you, it would quit responding when I would click on "Capture", but I managed to get the program to work properly by:
- Right clicking on the PD6 icon on the desktop
- Clicked on 'properties'
- Clicked on the 'Compatibility' tab at the top of the window
Where it says "Run this program in compatibility mode for:' , make sure you check that box and have it run under Windows XP (service pack2).
I did that and it worked like a charm. I hope that this works for you
