I have a user whose Tab key stopped working, but only on its own. That is to say, Ctrl-Tab, Shift-Tab, and Alt-Tab all still work. After swapping with a known-good keyboard, Ctrl doesn't work, and escape opens the start menu (which would indicate that ctrl is stuck down). After a second keyboard swap, with a keyboard that is known-good, tested, and absoutely pristine, he reports that the F key and Ctrl key sometimes do not work, along with a couple other keys.
No accessibility options are active, and the BIOS on all machines in this office are identical. What could possibly be going on here, and what can I do about it?
