+
+
+If one uses a short list (max 8 items) that does not trigger a scroll bar.
+When one selects an item and then attempts to select another item, any
+items prior to the recently selected item have been removed from the list.
+
+
+
+Expected Results:
+
+One should be able to select any item from anywhere in the dropdown list,
+items prior to the recently selected item should not be removed from the
+list and, when there is a scroll bar, the application should not crash.
+
+
+How often does this happen?
+
+Every time
+
+
+Additional Information:
+
+I am using Mandriva Linux 2006.0 with the SuSE 9.2 RPMs
+
+I have tested this with the Microsoft code I published on Mono-List and the
+code I retrieved from
+http://svn.myrealbox.com/viewcvs/trunk/winforms/combobox/swf-combobox-single.cs?rev=40235&view=markup
