heres 2 screen grabs before and after. while navigating between 'spaces' using mission control in mountain lion. issue - the menu and tools bars disappear - not all of them just parts of them. to get back i hit 'tab' button twice which hides and shows tools. very annoying - does anyone know of a fix or is this another bug which i have to live with. im using a macpro june 2012/running 10.8.4 and 2 screens - left for artboard - right for all tool windows.
