Hrm,  I'm getting a runtime error:
rcaskey@r3wt:~$ mono Wilkins.exe
 
Unhandled Exception: System.NullReferenceException: A null value was
found where an object instance was required

I am just stumped by this and have been working on it for a few days,
got a good hint from Lluis Sanchez(thanks) earlier but I still can't get
it to work right. Any help would be...err..helpful.

Thanks,
