The best help is to tell you to run Firefox. As far as I know, there
is no IE for MAC, so the only fully-supported browser for your use is
Firefox. Other browsers DO work, but they aren't fully supported so
you might encounter problems. Firefox is fully supported and used by
quite a few of the users in this group. It will greatly increase the
amount of support you're able to receive from both GMail and fellow
users like us.
