I've buyed a touchscreen lcd (
http://cgi.ebay.com/ws/eBayISAPI.dll...:X:RTQ:US:1123) and I'm experiencing some trouble with the touchscreen.
I used the supplied software to calibrate the touchscreen and all seems ok but after some working time the right side of the lcd starts to be uncalibrated so that i touch in a position and the windows pointer goes in a rightmost position.
This behaviour make complicated the use in a car! I noticed that the right rear part of the lcd tend to heat up a lot; I'm thinking that this can be the cause of touchscreen resistive circuit malfunctioning.
Any suggestion on that? Did someone have experienced something similar before?
