I was able to fix this thing based on Jim Correia's clue:

What you've done is ....
started a menu tracking session while the table view was already in
the middle of a mouse tracking session.

So I removed my override of -[NSTableView tableView:mouseDownInHeaderOfTableColumn:].

Instead, I subclassed NSTableHeaderView (which, it turns out, I needed to do anyhow to patch around some other unpredictable behavior), overrode its -mouseDown:, and moved my code into there.

Now, it doesn't keep on trackin' any more, and everything seems to work.

If someone could point me to some documentation on a "mouse tracking session", I might be able to understand why my first approach didn't work.

Thanks,

Jerry _______________________________________________
