Client Disappears if I minimize it or Alt tab during a game

While just in the client if I minimize the game is disappears and I have to go in to the task manager and maximize the task in order for it to reappear. Same thing happens when I alt tab during a game or just click on my second screen. The game minimizes and disappears unless I bring it back up through task manager. I tried running the client fix and I tried reinstalling but it still happens.
