Actually, what must be happening is the keyboard controller misses one of
the "up" codes from one of the shift keys, and therefore it thinks the key
is still down.  The fix you suggest should work, but if it is happening often
enough to be annoying, there is probably something wrong.  I think that only
the keyboard controller (on system board) gets these codes normally, so a
failure would have to be firmware in the controller of hardware.  I see this
phenomenon, but not more than one per month frequency.
