using mouse via xterm window

[David Banning]

I presently access FBSD via an xterm window from within Windows using
X-Win32. I would like to be able to run a window manager or file manager,
but this exits with an error because there is no mouse attached to the 
FBSD box. 

Here is the thing - I -can- run xv (a FBSD image viewer from the ports)
from my xterm window and the windows mouse works fine controlling xv
as a gui application.

Is it possible to configure the Xserver to acknowledge the windows mouse
via the xterm session?
