I know this makes no sense, but I have to ask.   Ive been running great on Windows 7 for months (RC -> Final) ... last week I decided to DL the "Official" Multi Touch driver from HP's site.   No issues, driver installed and I had to reboot.   Right after the reboot, touch stopped working.   Thinking it was a driver issue, I did a Restore Point ->  No luck, no touch.   Knowing HP support I then did a full system recovery back to Vista and no touch either .... If I unplug the PC over night and then power it, I will have touch working for about 1 minute - then it goes out...   I think the Driver also updated the FW of the touchscreen, could that be the issue?

This is all on my IQ504t
