I've had this happen a few times, under various operating systems and
programs.  Usually it happens when something causes some sort of context
switch just as I'm pressing or releasing a modifier key, causing some of the
keyboard codes to be missed (?).  Usually, pressing and holding _all_ of the
ctrl, alt, and shift keys together at once for a couple seconds clears it up.
