The cure is to manually remove the EG cookie, or simply close/re-open Safari. Google has turned up some Safari cookie issues, but I haven't found a useful fix.
I'm having a cookie problem with Safari, where a patron can login to the
OPAC and use their account without any problem. Then, after logout,
they can never get beyond the initial index.xml again. Not to log back
in or reach another page such as an advanced search. Each click results
in the requested page quickly being displayed, then they are returned to
the initial page.
