Problem with the screen

Hello again.I have asked in another thread how to make my laptop not to shut down when I close the lid and I found out that I just have to change a set from control pannel.Now the online game I play keeps running while the lid is closed but after I open the lid again and I click on my game I get white screen.Any idea how to solve this?Thanks:)

Does the game minimise when you close the lid? I know some games have problem with minimising and then maximizing again, so this could be the games' problem, not windows problem. Try posting on forum for that game, maybe hey will know.
