I hadn't tried to run a test local in a while. I went to do this yesterday, and strangest thing. I couldn't even login to the application.
I knew that the newer Google Toolbar represented itself as a browser document, but having a G+ +1 button was the first time this broke anything for me. Testing From the .uitest file, I could find the Window, but not the document.
I could tweak the document search, but I disabled the Google Toolbar for now.
