Gdeskcal and Fedora

["Bradley \(FC2 List\)" <FedoraList@xxxxxxxxxxxxxxxx>]

I'm not sure if this is a Fedora question or Gdeskcal question. 

I have two machines that load Gdeskcal on startup. 
On one machine, the app shows up in the panel.
On the other it doesn't. 
I would like to have it not show up in the panel on both. 
Both machines are FC2 and Gnome.

Any suggestions for where to look?

Thanks,
Bradley
