+I made this into a complete sample which is attached.  I can't get MS
+.net to throw any exception when InvokeRequired = true.  I am testing
+on .Net 2.0.  What version are you using?
+
+The 3rd part looks a lot trickier.  Clicking the first button, closing
+the dialog, clicking the second button, closing the dialog, and
+clicking the first button again seems to always call the problem.  It
+looks like we are making a call to win32's EnableWindow that isn't
+returning, but I haven't looked into it any further.
