Install TOUCHFREEZE and see if that helps.
I have a relatively new HP touchscreen laptop (Tm2 1.33 i3, Vista) that on occasion experiences random cursor movement and clicking. I haven't downloaded too much software, and is low virus risk.
Once it starts, restarting seems to help, and it only occurs after the computer has been on for a while.
I have turned the sensitivity on the pad way up, but hasnt helped. The random motion/clicking definitely occurs when i am not even at the computer.
I'm not sure, but I think there may be some association with the HDMI cable being plugged in, but not 100%
Wondering if anyone has any suggestions or thoughts on how to fix or better diagnose.
