Yes, the client was WSFTP_LE. Further tests had the same results when 
moving 4  ~15MB files via WebDAV. The server on the XP box hung
and none of the files were moved. The client was the built in Web 
folders on Win2K. With the same client the Zope server on the linux box  
received the files
fine. I ran a Zope server on my Windows Me laptop and moved some files 
onto it with WebDAV from a linux box (Mandrake 9.0,KDE 3.0) and
though the largest (a CD image ~500Mb) files didn't transfer (it looks 
like I ran out of disk space on the system drive) the Zope server didn't 
hang.

That could be. My experience with Windows threads is at least five years 
old.
