Anyone any experience with SAW touchscreens? Ivve got one which Im=20
trying to fit to an LCD display but the SAW signal seems to be suffering=20
some sort of interference and the mouse pointer just jumps eratically=20
around the screen.

There are grooves cut in the edges of the glass to 'direct' the signal.=20
Does it need a foam rubber strip along the outer edge of those grooves=20
to contain the signal?
TIA
