I've just upgraded to FC3 from FC2. I used to be able to access certain properties for the program launchers in the application menu by right clicking and choosing properties. I can still access this dialog box, but all of the options are greyed out. I know I used to be able to change things like the icon and the name, but not any more. Does anyone know why? I've checked a lot of sources and they all say I should be able to do this. The Gnome docs say I should as well. Is it just my setup? Have I done something I don't know about?

Thanks a lot for the help.
