Champ select, mastery and champ (cursor over) windows were stuck in place.

In champ select, the mastery and the champ (cursor over) windows got stuck and I couldn't get out of them to select a champion without dodging........ this has happened before in the past, as well. Maybe add a way to either hit Esc or something so this doesn't happen again? I don't fucking know. It obviously doesn't happen often, but it is super annoying when it does happen.
