Thanks for the suggestion.  It certainly seems to have something to do with
sessions.  The user who is experiencing this doesn't use more than one account.
 The problem was happening fairly regularly, but went away (for now) after he
rebooted his windows computer.  Possibly he had logged in more than once to the
same account, and that somehow was causing it ?

I'll let the list know if I can find a way to reliably reproduce this.
