It sounds like some setting being configured while playing is causing the game to be unable to launch after you exit and reopen, are you making any settings changes when you get in?
If not does the in-game screen resolution (Options > Graphics) match what Windows uses?
It's a netbook so its not really a supported system but most likely there's a setting that its getting hung up on when it launches.
One thing if you exit the game in "windowed mode" (alt & enter keys) does the game relaunch in windowed mode correctly?
