hey all, I have an HP TX2 1275dx tablet PC with Win7. I'm having an issue with the cursor. It disappears constantly, but if I hit CTRL+ALT+DEL to get to the lockscreen menu, I see it again for a few more minutes! This issue has followed me through 2 hard drives, 2 operating systems, and many reinstallations of windows. All mouse and display drivers are up to date. Any ideas what could be causing this?
