I had the friends popup open, and then got pulled into a league match. When I finished that match, I couldn't make the popup go away. Clicking on "back" did nothing.
I also got stuck at the popup for friends. Was on the world map. Maybe related to my double-clicky mouse. Could not do anything, including accessing options or selecting the chat box.
I did check after the match, I didn't see any errors at the end of the log (after the match finished messages). There might well have been an error when the match began.
