vbpopup boxes allover the place :(

[peach]

I'm using the default theme, but at fixed width, and the vbpopup boxes are allover the place, the search, the more_smiley box etc.

I think I read somewhere that I should have used the default-fixed-width default template, but I already made many small modifications and plugin integrations... how can I fix the popup problem?

Thanks,
JR
