Minor client bug

I noticed that a minor client bug occurs quit frequently to me. When i press play to, obviously, start a game and then change my mind for whatever reason and go press the profile button well it pretty much doesn't respond. To say it more simply, when i press the profile it doesn't react and needs to log off the client and re-log to work again. I hope my English are good enough for you guys to understand what i mean, if you need further info just ask :)
