Invalid Signature with Desktop app

Jan 10, 2009 at 1:38 PM
I am trying to create my first desktop application. I am starting off using the DesktopSample project which works fine until I change the API key and Secret to my own app. I notice in Facebook it says that my application type is website and will not give me an option to change to desktop. When I run the DesktopSample I now get 'invalid signature'. If I change the API key and secret back it works fine. Any ideas?
Many thanks.
