Apologies, still getting to grips with this mac mullarkey. I downloaded Realplayer to listen to BBC stuff - all works great, but there's now a 'Realplayer' icon on my desktop, which I don't want. I made the mistake of dragging it to Trash, which just got rid of the plug-in!! Downloaded it again, so how do I just shift the icon without losing the application?? I can drag it to the dock, but it still leaves the desktop icon.
