Off the top of my head, and keeping your current approach, you can check for a selection in the other OV before attempting to clear the selection of itself. I.e.: 1. User clicks in OV#1 2. OV#2 delegate receives -outlineViewSelectionDidChange:; checks to see if OV#1 has a selection, if so, clears OV#2's selection. 3. Clear action of OV#2 causes OV#1's delegate to receive -outlineViewSelectionDidChange:; checks to see if OV#2 has a selection, which it shouldn't since it has just been cleared, so does nothing. This should be properly reversible (i.e. should work equally if you swap #2 for #1 in the above). Alternatively, you could implement the "clear" operation in an action method invoked by the OV (don't forget to check -clickedRow). HTH, Keary Suska Esoteritech, Inc.
