Don't do that. Same as the other thread about tty. Use this instead:
xpra start :DISPLAY --bind-tcp=... --start=COMMAND

You're not sharing your multifile password file, so I won't be able to
reproduce what you did.

You're also not showing what versions you've used for testing, the only
version shown is from the win32 client, which is well out of date:
> Python/Gtk2 Microsoft Windows 7 client version 0.16.3-r12203

There's a debug flag for authentication, try adding "-d auth" to your
server command line.
