 * Hey … I am have the same issue … but I noticed when I first installed the plugin
   I got a WordPress error saying
 * “The plugin generated 4 characters of unexpected output during activation. If
   you notice “headers already sent” messages, problems with syndication feeds or
   other issues, try deactivating or removing this plugin.”
 * You will see it if you deactivate / reactive the plugin … seems like it might
   be a whitespace issue … but I am not good enough at php to know exactly what 
   to change …
