Do you have any add-ons installed? Things like stylus? I've seen this before where someone had a css edit installed that was erroneously affecting the roll20 site.

I got Beyond 20 and VTT Enhancement suit installed, not sure its an issue.  Anyway I can live with that bug/glitch, just wanted to point it out.
