A workaround AppleScript to allow launching PandoraJam when ClickToFlash is installed. (Details on how ClickToFlash breaks PandoraJam can be found here.) Dead simple operation: it moves the plugin to your Desktop long enough to launch PandoraJam, then puts it back. The script doesn’t handle permissions at all, so if you’re using a non-admin account and the plugin is in your top-level Library, you may be asked for an admin password, or denied access.
I’m shipping this as an application to make it easy to use — just put it in your Dock (or redirect Quicksilver or Launchbar to it), and use it instead of the PandoraJam icon when you want to listen.
