Ii have touchscreen issues with two totally different systems both high end windows 7 - 64. I am using a lilliput 10" USB touchscreen on a rackmount industrial pc and upon boot to desktop only 30% of the time the cursor is erratic and clicking, double clicking and draging things all over the screen. Only option is the hard reset pc. This system only uses windows 7 drivers. Also I have an unrelated highend Stealth.com system running same platform and installed programs (single purpose industrial setups) that uses the 3M touchscreen drivers and has same issue only on some of boot ups.
Any ideas or help is appreciated.
