We found some problems with IE 5.0 so we disabled it in the user side, but not in the admin. You can change it in GMail.pm line 389:

unshift @opts, { is_ie5 => ($ENV{HTTP_USER_AGENT} and $ENV{HTTP_USER_AGENT} =~ /MSIE 5\.5/i) ? 1 : 0 };

Change MSIE 5\.5 to MSIE 5 and it should work for all ie 5+.

The problems we encountered were:

1. The right click menu did not display properly.
2. On some installations it would pop up trying to install Office 2000.

This wasn't on all IE 5.0's, just some we encounted in the office.

Hope that helps,

Alex
