 At least downloaded page seems complete.

 I assume that http server should close connection (by doing close(2) on
socket), not client or proxy (if user doesn't terminate transfer). 
Since proxy code that handles connection is probably simple (so it less
likely to contain bugs), and proxy has not noticed the fact that socket was 
closed (if it noticed, a line from the status window would have been removed),
I conclude that Windows TCP stack is broken. I used Win95 with very
old TCP stack implementation (WinProxy suggested me to upgrade my TCP stack
during installation with a newer one - and suggested me URL, but I didn't).
Another point - seems WinProxy is bug-less (I hope) - seems they sell a lot
of copies to be reach to fix bugs.
