Doesn't work in a site-specific browser (aka Fluid).

I used Fluid to create a SSB for Threadsy, so I can put an icon on my dock (Snow Leopard) and just launch Threadsy in its own window. The Facebook connect dialogs are not at all happy with this, though, and end up opening in other windows to blank pages, the SSB gets extra windows, etc. Just doesn't work.

(I know that in the early days this is an edge case, but thought it was worth reporting anyway.)
