On OS X (I haven't checked on Windows), a modal dialog box in Radio-the-desktop-app will completely freeze Radio-the-desktop-website. This causes a problem, because when I turn Upstreaming on or off from the Dock, I never actually see the dialog box that pops up to confirm it, and then I run around in circles wondering why the website has stopped responding entirely.

I'm offline right now, this post is mostly a reminder to myself to post the same point to the discussion group when I get home.
