+Summary: InvalidOperationException in SWF
+
+I saw a small glitch in the drawing of a MessageBox window, so I was
+dragging the window around to reproduce the glitch. As I was dragging, the
+following exception occurred. Afterwards, my program was completely
+unresponsive - would not even repaint - but the MessageBox window could
+still be moved around (though it would not repaint either).
+
+Unhandled Exception: System.InvalidOperationException: List has changed.
