Sylvia Philemon

My avi has this weird rectangular screen floating in front of her face. It seems to reflect some of the scenery of the sim, and changes when she moves. Also, and this seems to be related, her hair is all messed up. I've tried a variety of things but this happened once before and the only thing that made it go away was to uninstall and install the viewer (viewer 2). But this time, I've done that three times and it makes no difference. Still there.
