+It would be nice if somebody could test that "value" weirdness too.
+
+Replace ComboBox.SelectedIndex with the following version:
+
+public override int SelectedIndex {
+			get { return selected_index; }
+			set {Console.WriteLine("value first time: " + value);
+				if (value <= -2 || value >= Items.Count)
+					throw new ArgumentOutOfRangeException ("Index of out range");
+    				selected_index = value;
+
+    				if (dropdown_style != ComboBoxStyle.DropDownList) {
+					if (value == -1)
+						SetControlText("");
+					else
+						SetControlText (GetItemText (Items [value]));
+    				}
+				
+				Console.WriteLine("value second time: " + value);
+
+    				OnSelectedValueChanged (new EventArgs ());
+    				OnSelectedIndexChanged  (new EventArgs ());
+    				OnSelectedItemChanged (new EventArgs ());
+				if (DropDownStyle == ComboBoxStyle.DropDownList)
+    					Invalidate ();
+
+				Console.WriteLine("value third time: " + value);
+				if (listbox_ctrl != null)
+					listbox_ctrl.HighlightedIndex = value;
+			}
+		}
+
+Now run the FileDialog sample, click the upper "Search in:" ComboBox
+button to get the dropdown listbox and select an item somewhere below
+the currently selected item.
+
+Here I get an ArgumentOutOfRangeException with the following Console
+output:
+
+value first time: 8
+value second time: 8
+value third time: 8
+value third time: 13
