[thelist] Odd file download problem in IE 5.5

[Chris George]

Hey all,

I'm having a problem with a PHP file download script a friend/colleage
of mine wrote for a client. We've been struggling with caching issues
all along, where by when someone chose to download a file, it would
attempt to bring up a cached version, usually resulting in an error.
This latest one is along the same lines, however I had thought we
cleared it up. When a user clicks on a file (which happens to be Excel)
(which doesn't happen on any of my test machines, or some other remote
machines we've tested it on, so far), it brings up Excel in the browser
(the way it should), but instead of the file in question, somehow tries
to display the login screen of the script. Very odd.

Does anyone know what we are experiencing, and what we can do to fix
this? I've included some screencaps:

Any help would be greatly appreciated! Especially because I *need* to
bill them!

Thanks!

Chris.
