I usually find that LW blanks its screen when I am either minimising or expanding it and, usually, when I have some other programs running at the same time. But in my case, I eventually get my screen back when windows hands back resources to LW.

So, if you are running LW while running other apps I suggest that you don't anymore - I am assuming that your O/S has switched some resources away from LW and is sharing it among your other active apps.

Hope this helps
