I have a Dell Precision M4600 (with capacitive touch screen) running Windows 8. Normally, I connect two monitors via docking station and keep my laptop closed. When I undock and use the laptop without touching the screen, everything works fine. But when I touch the screen for any reason, after a while (between 3 and 6 different touches) the screen will start registering touches all over the place, though mostly at the top. This means windows randomly open and close, which of course renders the computer unusable. After a reboot the behavior will start again (if I begin to touch the screen).
There used to be a way to turn off the touchscreen, but this option is gone in the RTM.
Dell "does not yet support Windows 8" and would require me to install Windows 7 before they will troubleshoot a hardware problem.
Any ideas on what to try to either a) prevent this from happening while using the touchscreen or b) disable the touchscreen when this starts happening?
