Every once in a while (every couple of hours to every couple of days) the keyboard on my notebook stops typing, and instead does things like pull up menus or do other weird things, seemingly at random. For a long time my only option was to turn off the computer and reboot, but then I discovered through random chance that holding down the Windows key and then tapping alt returns things to normal, and allows me to type again.
What I do not know is -why- this happens, or why this fix works for it. And I would prefer not dealing with this at all. Does anybody know -why- this happens?
