Possible Bug? Or just me?

When I Re-Size the TGB Window while editing, it gets all messed up. Changes windows to diffrent things, and buttons are unclickable/behind other things, ect. The only way i can fix it is to close it, relauch it, and hope i Didnt save before hand or i get the enw saved messed up screen. Is thier a way to revert? :(
