[Zope] File Upload returns "application/octet-stream", not correct type

[Joel Burton]

This is possibly a browser error, rather than a Zope error, but I can't
find any references on the web for a browser bug.

When we upload to Zope (via a form that we build, or by simply adding a 
"File" object through the management interface), it comes out as
"application/octet-stream" rather than as the appropriate MIME type.
This only happens on one computer (Win 98, IE 4), suggesting a browser
bug, but I can't find any references on the web about a problem with this.

Does Zope do any mangling at all of MIME types? Does anyone have any ideas
what this could be?

Thanks for any help.
