+Summary: PropertyGrid with UITypeEditor not showing dropdown
+
+I first reported this bug on the mono mailing lists.  It was deemed a bug,
+so I'm just going to paste the email here so that you have it for your records:
+
+> I'm having a problem that I can't seem to figure out.  I created a
+> class that has a public property with an array of enums.  I would like
+> to have an Editor that allows the user select 0 or more enums to
+> populate this array.  My problem is that the PropertyGrid won't
+> display either the elipses or the dropdown button for me.
+>
+> Below is an example of the how I have the classes set up.  When i
+> create a PropertyGrid and set the SelectedObject to an instance of
+> ClassToEdit all the properties show up how they're supposed to except
+> for the array of MyEnum.
+>
+> Any hints?  I've looked through the MSDN and it looks like I'm
+> implementing this just like all of the examples.
+>
+
+This looks like a bug, please file a report here: http://bugzilla.ximian.com
