After one game, the client will appear at the bottom of the screen, and I can not drag it back to the center of the screen. It happens several times now, and it is very annoying because I can not even change my mastery, ruins, and spells in the next game.
PS: I use Mac.
This board is the best place to discuss the client with Rioters and your fellow players, although it won't be our main source for feedback resolution. Look to the other tools, like the Submit Feedback button in the client, for that. As always, please follow the Universal Rules and keep content focused on appropriate topics for this board.
