I tried to put in a new video card yesterday, which turned out to not function at all with my computer. So I put the old one back in. When I once-again fired up AR, I get the screen below when I go to make a post. The area to post is now to the right, and half of it is off the screen. Before the failed attempt at the new video card the posting area came up on the upper left, with all of it on the screen. Any ideas why I'm seeing this now?

Did you try resetting the screen resolution in "Video Properties"?
