Up until a few months ago, my colour touch screen had been working flawlessly for 6 years. Recently it has stopped responding to touch and I have to regularly reset it. After the 1st few times i did a firmware upgrade and reloaded the project which seamed to work however this was short lived as it started doing it again and now i have to reset it at least once a day (sometimes twice) to get it working again (I've given up putting the GF back on!) I've tried plugging a KB in and it is not recognising anything plugged into the USB ports. When its working, it works fine and I have not made any changes to the project - it has remained virtually unchanged from the start. I'd like to try a new CF card, incase mine has become corrupt, before I fork out for a new screen but tech support advised that new CF cards were no longer available. Any suggestions?
