After closing the popup window all of my buttons were dimmed out and cannot be clicked except for the AH and friends buttons. This bug was reproducible for me via choosing public games, clicking join a game, and finally clicking cancel to let the queue timer run down to zero as it would produce ERROR_25012 after I clicked cancel. The timer would continue while the popup for the error was still on the screen.
Logging out and back in allows access to the buttons again.
