I just want to throw this out there: Both the Google Analyticator and Popularity Contest plugins render the Wibiya toolbar unusable in webkit browsers (and possibly others). With all other plugins off, enabling either of the offending plugins along with Wibiya toolbar will result in a toolbar that cannot be clicked.
Of course, this could just be me. Fortunately, I was able to find a simpler Analytics plugin that doesn't break Wibiya. Unfortunately, my theme has Popularity Contest built-in, so it loses functionality when I disable it.
