someone said something about a wave screen or board?? does that sound like anything to you? Thank you by the way for your help!
It doesn't mean anything to me, but I'm not a tech. I've messed around with half dozen old touchscreens for jukebox builds and megatouch replacements.
That's as far as my experience goes (and it was usually trial and error). Half of them were serial, but I never used Win7 with any of them.
My next step would be to try to use it with a computer running XP.
If it does, then you know it's something to do with the Win7 drivers.
