 Using MWF but MS runtime and System.Drawing on WinXP I don't get any 
 exceptions. All four datagrids come up properly. Can you provide any 
 details on when this is happening? Or maybe a full stack?

+I used Mono SVN r54150 on Windows XP.
+
+mono --debug swf-datagrid.exe
+
+Without any window being displayed it crashes right after it is 
+executed.
+
+Full stack trace:
+
+Unhandled Exception: System.NullReferenceException: Object reference 
+not set to an instance of an object
