Hello, Here's a link to a very short video (MOV format) showing the issue that I'm having. I'm guessing that it's CSS related. It seems like the screen update shouldn't be so obvious. The graphics involved are very small, as well. What could be causing this? Thanks for any help! blendernewbies dot com slash tmp slash screen_update_issue dot mov EDIT: well, it seems I can't post links! How am I supposed to accurately convey the issue without wasting people's time trying to describe it? Sigh. I will try to post the link in a written out format. I hope it doesn't violate anything doing it that way. The video is hosted on my own server and is about 800KB. Thanks.
