On my website I have a picture of an Xbox 360 as an avatar for users that have no avatars uploaded. I have tried multiple different "No Avatar" avatars and a couple of different pictures, but I keep getting the same problem. In profiles if a user with no avatar posts a visitor message, their text runs over onto their "No Avatar" avatar. I don't know if this is the code or the style or what, but it also happens on the default vbulletin style. Here is a screenshot.
Any ideas on how to fix?
