Thanks Reinhardt.  Installing an eventFilter seems to be the required solution to fix the incorrect QComboBox behavior.

Is there an easy way to prevent this unexpecetd behavior?

Or does it require replacing al QComboBox items with a derived version that
filters events?

Install an eventFilter on the QComboBox?

I was hoping that focusPolicy would provide an easy solution.  Neither StrongFocus nor NoFocus prevents this behavior.

This behavior is considered a bug in the QComboBox behavior by *both* OS X and Windows users.
