Using mono 1.1.6, I tried running a simple basic
windows form and got the following.

# mono monotest.exe
Mono System.Windows.Forms Assembly [Revision: 41731;
built: 2005/2/15 5:56:12]
Keyboard: VNC keyboard layout

Unhandled Exception:
System.TypeInitializationException: An exception was

Any ideas what the problem could be or if mono has a
bug that can be fixed?
