But if the 2nd call to validateMenuItem prior to the action is new and intended behavior in Leopard, I'd like to know what the purpose is so I can code appropriately.

Hi Doug,

The second validate is to allow programmatic calls to performActionForItemAtIndex: to work correctly with auto-validation. It should not be invoked in the case you are seeing, but apparently it is.

Have you considered using the clickedColumn method of NSTableView to avoid having to do your own mouse tracking?
