The way to fix the Blank screen on startup
There was a 600 x 800 res bug inadvertently introduced into LW 11-12 mths ago but this was eliminated fairly quickly. Sounds like video card settings such as those for 3D. Looks like you may need to keep switching it between each time you play the game & when you use LW.
