When you are in Champion Select, if you edit your masteries and press spacebar three times...
Your Masteries page will freeze, thus blocking ou from picking a champion/changing runes, etc.
Just warning you guys.

This is actually pretty important. You should put up a topic in Bug Report, too, if you haven't already. This needs to be fixed.
Tried this cause some guy said to, and ended up dodging in my promos on accident. :\
