Installed on OSX, nothing seems to work

[Robert Konigsberg]

I'm not sure how to proceed here -- I managed to manually install ScriptCover (considering adding this tot he Chrome Web Store?) and when I restarted, the JS extension icon appeared, but whenever I clicked on the icon, an extension popup bubble appears, but remiains a small square. There's not much more information I can give you. Please advise. Thanks!
