Load in is minimizing istelf and wont open even after load in.

My last game I was support and the champ select worked like usual. As soon as it got to load in the screen popped up then just dropped down and wont open up or stay in focus on the screen. Now it didn't even let me open it up after loading into the game. It still just kept minimizing itself and would not stay up. I apologize to the people who were in that game because i couldn't play and cost them as well.
