F6 Button getting touchy

Recently my F6 button has not been working all the time. I might have to hit it 3 or 4 times to get it to work. It has always sat a little lower than the rest of the F buttons(along with F5) but has never gave me any problems before now. Anyone ever had this happen before?
I'm thinking about taking it apart and and taking a look inside tonight to see if its anything I can fix.

yeah, I just recently had to take the cover offa mine and super glue the PLAY/START button back...not sure if thats the problem but its a start.

It's probab;y the tact switch underneath.
