League Client (Open Beta) Issue

Problem caused by issue: Unable to accept/decline the match-accept process (the ready process? W/e League calls it lol). This forces a ready-up decline and possibly an unfair time limit on your next queue up.

Reproduction steps:

1. Queue up for a game.
2. Since the games sometimes take AGES to start up, start browsing the store! Check the recent sales, etc.
3. Get curious about the (IN-STORE) "Account" button.
4. Click said "Account button." Notice: Step 4 and 5 happen ALMOST simultaneously, though step 4 happens (at least, client-sided - idk about what your servers claim) JUST before step 5.
5. Ready process pops up (asking you to Decline or Accept the ready check).
6. Profit! Kidding ... The now-broken (I show this champ cause he's also BROKEN) "Account" window, which is basically unusable and frozen, is in front of everything. BONUS:
7. The now-broken "Account" window is STUCK on, unable to be exited OR interacted with, forcing you to force-close the game using ctrl+shift+escape (aka Task Manager).

Good luck fixing it :) Hope my steps help.
