It's kinda sad that the news booted her story out the way. I didn't hear about her until later on tonight after I heard about Michael Jackson. I don't really know much about her except she played in Charlies Angel because my mom watched it in the 70's.
I think that might be a graphics problem. That happen to me before I updated the latest drivers for my graphics card. And I haven't seen that happen since. Try updating the latest drivers to see if that helps.
