Control key stops working after waking from sleep

[yossren]

I have my Mac set to sleep after 1 hour of inactivity. After I wake it from sleep, SOMETIMES I find that the Control key no longer works. It doesn't always happen, probably about 50% of the time. If I pop open the Keyboard Viewer, I can watch and see that hitting the control key has no effect. The rest of the keys on my keyboard, and my mouse, are just fine. I haven't found any way to fix it except to restart the machine. Even the Change Keyboard Type wizard doesn't help.

Has anyone else experienced this problem before? Any ideas on how to (a) keep it from happening or (b) fix it once it's happened (besides restarting)?

Thanks,
Jed
