We are all confused. Sorry if I gave the impression that I understood
the problem. It is not reproducible at w3 (they use NT), but many windows 98
users get the problem.

Possible areas for investigation.
1. IE4 (http 1.1, accept png) verses Netscape 4.05 (http 1.0).
2 Win98 verses NT
3 Directory aliasing (www to WWW)
4 Content type negotiation. (png and jpg or gif)
5 Reported content types in headers.

My own suspicions now lie with the complex operations associated with
redirecting frames while keeping alive an http 1.1 connection. I have seen
connection breaks, requests with no URL (protocol error), and HTTP 100 continue
messages in the display area of my browsers.

I also once saw Window 98 explorer "wobble"
(alter behaviour) when exploring png files (no IE browser, no jigsaw, no network)
but I
have not been able to reproduce it.

Please can you diagnose the problem (use a -trace option when starting the server).
