Not sure how to explain this but sometimes I will be working, usually with a bunch of windows open (RDP, VMs, etc) and then I'll switch back to a web browser or notepad and I'll start typing. The system acts as if I'm pressing key combinations while holding the windows key. For example, if I press 'E' the my computer window will open. If I press 'Space' then all windows will go transparent. It's as if the windows key is stuck on (of course the physical key is NOT stuck in any way so cleaning the keyboard isn't a solution).
This happens on all of my systems as one point or another. (WinXP, Vista and Win7)
- why does this happen?
- how do you fix it without rebooting?
