I've tried to find the solution but cant seem to find it. My task bar, the place where the programs minimize to stop responding. Like I would minimize say Firefox and when i try to click it again it does nothing. The only way I can bring it back is to alt-tab the program to the front.

Thanks in advance.

erm.. what theme is this?

Sorry, its Fleep-Reliction but it seems to occur with any theme over time.
