The other day I was happily using my laptop, several tabs loaded in Chrome, when I apparently hit some key sequence, one of the tabs moved to a separate window, my cursor disappeared and my touchpad stopped working. After two days of trying everything I could find searching for solutions, and finally deleting the touchpad and letting Windows find it again, it's mostly working - the cursor is back, the touchpad moves it, tapping works - but the buttons don't work. The Dell Touchpad panel shows the buttons enabled, but they aren't. Is there anything I can do to get this working like it did Sunday morning at 6:30, not at 6:31?

Thanks,

Harry
