Client side bug when someone dodges.

Okay, so I have experienced this previously, and it is quite annoying, there is no way (other than restarting the client) other than getting into another lobby to fix this. so what happens is, if you have your cursor over a champion icon when choosing who you want to play, and someone dodges, the champion's splash art appears on the home screen, and you can't remove it. note it only happens when you have your cursor over a champion and someone dodges/does not pick a champ.
