[horde] Horde3, redirect.php, IE, and Blank Pages

[Mark Hennessy]

I have found that with Horde3, even with the newest version 3.05, that if one
of my IE users tries to log in and fails due to bad password, they get a
blank screen and the URL in the location line ends in redirect.php with no
further activity.  I was wondering if anyone else had observed that behavior
and what might be done to remedy it.  If not remedy, then at least what might
be done to attempt to determine the cause of the behavior.  I have not
observed this ever with FireFox or any other web browser.  The server is
using FreeBSD 4.11 with Apache/1.3.33 (Unix) PHP/5.0.4 mod_ssl/2.8.22
OpenSSL/0.9.7d and Zend Optimizer + Zend Platform although we have observed
the problem with PHP 4.3.11 and no Zend as well.

Please advise.
