Keyboard stops working a few minutes after boot

Hi,

I've just installed the Lion release from the App Store on my 17" MacBook Pro (2010).

About 5 minutes after boot, the keyboard stops working.

It will respond to ctrl-num to switch spaces but will not respond to any normal keystrokes in any app or system dialog (including the login password entry).

Tried an external keyboard and that doesn't work either.

Only option is to turn off, turn back on and it will work for a few minutes before stopping again.

Any ideas?

Thanks,

Ian

MacBook Pro, Mac OS X (10.7)

Well I've fixed the problem on my machine. It seems I had the Universal Access option ticked to 'Press the option key five times to turn Mouse keys on or off'. I usually tap my fingers on the modifier keys, when it was option I would disable most of my keyboard not realising what I had done.
