Firefox + Flash + OS X + Keyboard.... Question?

My keyboard stopped working when playing Flash games within Firefox. It works well with every other aspect of Firefox. It just refuses to work when playing flash games.

Does anyone know of a fix? And this happened around the time I upgraded Flash. That was about a week ago. I would be happy with directions for going back to the older version of Flash too. I assume that the upgrade was the problem and I just noticed.

OS X 10.4.11
Firefox 2.0.0.11
Flash Player 9.whatever

Edit :: Same thing happens in Safari..
