No.  I think the issue is that Windows is catching the wheel click event 
before it gets to the application.

Left button is assigned to Context Menu, which maps to emacs mouse-1. 
Right button is Primary Mouse Button, mapping to emacs mouse-3.

The mouse properties dialog lets me assign the wheel to many things: 
recycle bin, maximize, C-c, escape, Fn keys, etc., but none of them maps 
to the emacs mouse-2 event.

FWIW, my work around is to assign the wheel click to F3, then assign F3 
to my desired mouse-2 behavior - yank.
