Internet Explorer forgets my login!

Firefox works fine, but using Internet Explorer 6.x I can log in fine, but
as soon as I click on something it brings me back to the login screen. I
then have to log in again, when it will take me to the page I previously
requested.

Any ideas??? I’m going slightly mad…

Config info below…

RT 3.4.2 on Gentoo. All prerequisites are satisfied except 'make testdeps’
reports:

    Storable 2.08...MISSING
            Storable version 2.08 required--this is only version 2.07 at

(eval 37) line 2.

But this is rubbish - 2.15 installed fine and there are no references to any
other versions on the system.

Apache 2.0.50 config section:

Alias /rt "/opt/rt3/share/html"
# this line applies to Apache2+mod_perl2 only
PerlModule Apache2 Apache::compat

PerlModule Apache::DBI
PerlRequire /opt/rt3/bin/webmux.pl
<Directory /opt/rt3/share/html>
  AllowOverride All
  Options ExecCGI FollowSymLinks
  Order allow,deny
  Allow from all
</Directory>

<Location /rt>
  RewriteEngine on
  RedirectMatch permanent (.*)/$ $1/index.html
  AddDefaultCharset UTF-8
  SetHandler perl-script
  PerlHandler RT::Mason
</Location>

Cheers, Alex.
