Might be a one time occurrence, who knows. Picture attached, and here are the details:
- Windows XP SP2
- Firefox 2.0.0.11

 

Hmm That's strange. I'll have to look into that. It's never happened to me so I have to figure out how to replicate it.

 

Yeah, reproduction is always fun. I have never had it happen before either. Let me see if I can replicate it with exact steps. Maybe it was a specific entry point into the section.

 

I've had it happen (not quite so oddly spaced) from time to time in FireFox at home, my old computer and at work. It may just be a thing with how Firefox accounts for banner ad sizes when a page is loading. It always seemed to happen to me when the page load was acting up.

So it's likely vBulletin and Firefox not playing well together. No idea if anyone has experienced it with any other browsers.
