Every now and then, somehow, this happens (see the tab preview that opens in Firefox on the screen on the right). This happens as well with tooltips - sometimes they get stuck on screens where they shouldn't be, and the only way to fix this is to do whatever re-shows the tooltip, but that only works to move it sometimes. Like this time, whenever I drag a tab to the right screen, it moves the tooltip, but once I let go, it doesn't remove the stupid overlay.
I'm sure I'm not the only one who's experienced this weird problem on Windows machines. Anyone know how to fix this without rebooting?
