Believe me, I tried that... normally F2 hides/reveals it for me but when its gone theres nowt that be done. The only time I've got it back without a re-install was when it sorta appeared at the 'non-visible' area of my second monitor. This area is where my primary monitor is a higher resolution than the second.I've tried scrolling down the window etc. but no joy.

Its not the most earth shattering problem as I can live without it its just there are times when its more convinient when it there
