Session Expired

Yeah this has been around for years, how has it not been fixed yet? Whether the necessity for this screen exists or not, shouldn't it just open a new shop window ffs?

Secondly, when a player is messing with something in the client window (runes/masteries/shop/champions/etc), and a game pops (which often doesn't get accepted by everyone or make it through selection to start the game), it'd be nice if the client would revert to the exact same client window and situation that they left it in. Just saying, seems kinda obvious..
