It's not windows dependant. I have a convertible netbook/tablet pc since several years with XP, and it's the mouse that is controlled by the touch screen functionality and that works for any program, also within VFP.
I've seen ideas using input of a webcam, eg following multiple marker objects. What are you referring to, that would be special to Win7 regarding touchscreens? Or using normal TFTs?
