My Surface 2 Pro has started doing something pretty weird. Sometimes, when I am typing on my Type Cover 2, I'll suddenly see activity as if I was also holding down CTRL or maybe ALT. For example, if I started typing "for" in this post I'd see the "find" box pop up, as if I pressed Ctrl-F. I'm not positive it is a stuck Ctrl key, though--still trying to work out which key(s) it is. Here's the weird thing. You'd think it was the cover at fault, right? Driver problem, or maybe an actual stuck key? Well if I remove the TC2 and summon the Win8 on-screen keyboard, the problem persists! You just can't type normally, it's like a modifier key is being held down too. I tried summoning the "Ease of Access" on-screen keyboard because it shows you what keys are pressed on any attached physical keyboard--nothing was lit up. Switching to the desktop seems to clear the condition. I tried a 2-finger restart for kicks and it didn't prevent the condition from coming back. So far I have only seen this in Chrome and Office 2013, but that's just what I have been using for the last couple of days. I have not installed any new software lately except for USB drivers for a cell phone. I'm going to try purging them, of course, but does anyone have any other ideas?
