Take a look at config.h; there dwells a section in which you can set the default desktop an application will belong to. By default, it comes with Gimp and Firefox configured, and if I'm not mistaken, Firefox is set to desktop #9.
Ah! Did you install dmenu messages display? It's a very cool addition. Again, config.h comes configured to modkey + p launch dmenu showing all executables from $PATH, then one can use it to exec apps.
