This is a problem inside PitStop Professional.
The workaround for now is to go into your System Preferences and choose Displays. Choose a large resolution like 800x600 and then reposition your Windows/Pallets lower in the screen. Then switch your resolution back. Or hide the menu (Apple-shift-M) and move the Window/Pallet.
