auth: IE4 hangs on failure

I'm trying 1.2beta22 on a SunOS system for testing... I've enabled the
directives

acl password proxy_auth /usr/local/squid/etc/passwd
http_access allow all password
http_access deny all

When I access the cache through Netscape 3, and I type a bad
username/password, all is good... get a auth failure, and a reprompt.
With stupid IE4, however, access hangs for a couple of minutes (seems
like the browser is still reading while the username/password dialog is
still up) and finally times out after several minutes.

The really bad looking thing is the squid goes into an infinite loop of
'FD closed?' messages (shown below). I append the relevent log entries
for the IE4 access

Has anyone tried IE4 with 1.2beta22 and proxy_auth? Is there a patch to
fix this? Seems like a file descriptor is still alive and IE4 lingers
on it...
Thanks in advance for any advice.
