ok heres one for you, i am having similar issues with my TM-868, it calibrates fine, works fine, then for some reason the touchscreen loses connection with the drivers. I can still see the desktop, but no touchscreen. btween 5 and 20 mins on the average that i have noticed. it is intermittent, not always on a time schedule. as soon as i discon and recon the usb plug all is well. ive used both old and new drivers with no change. trying to use the TB for rfactor racing. any other ideas that i might be missing ?
