Google Deskbar

I just downloaded the Google Deskbar and the development SDK. I've written the infamous "Hello World" and I'm planning on writing some more plugins here in the near future. The only thing that's a little odd is how you load and unload the plugins. You load them by placing the dll in the plugin directory. Unloading is another story. You're supposed to hit some key sequence to unload all plugins but as soon as you unload them, they are reloaded! Thus making it pretty difficult to update/test a plugin. Maybe its just PEBCAK but then again, there's not a lot of documentation about on the API....
