Hey guys I've got a very strange problem with my touchpad, for some reason it keeps disabling itself, whether a USB mouse is plugged in or not. It is enabled in settings, it responds to commands (its not dead) because I see the icon on the task bar light up every time a button is pressed or my finger moves over the pad.

It is only disabled when I log on...so frustrating!! If I log off, on the choose user screen, it works!! as soon as I log in and my desktop is shown, it doesn't work at all! Reinstalled drivers, tried enabling/disabling touchpad using Alienware control center and device manager.

How can something so trivial be causing so much havok? Could some spyware/virus be doing this? Cheers.
