Applications not appearing in GUI
 

I am running GNOME on my LInux Enterprise Version 4. When I click on an icon to open an application, for exampe, Printer settings. The swirling arrow appears, indicating that the application is loading. Then, nothing pops up. What's up?

Have you tried to start your application from a terminal?
If you type the command to your app at a terminal and it doesn't load, you should at least get an error message. Try this and if you get an error, post it here. That'll help to find out what's going wrong.

Thanks, - Follow UP Question
 

Thanks for the reply. Could you tell me how I can discover the commands/names of the applications that will launch the application from the terminal? hk

The easiest way to do so is to install the Alacarte menu editor.
Assuming "LInux Enterprise Version 4" means RedHat Enterprise Linux 4, do
If you take a look at the menu entries with alacarte, you'll find the command to each entry.

I don't use GNOME, but I'd be very suprised if it doesn't already have some means of editing menus built in.

actually it doesn't have a very good one, you have to edit .menu or somethign entries in some deep dark directory, and it isn't very intuitive at all. I steer well clear of gnome these days.

suppose you are running firefox just type firefox in the terminal, suppose gnome editor type gedit, suppose calculator type gcalc and hit a tab it adds the rest.
