I spent a little time researching this, and didn't come up with any
good solutions.  The problem is that the pop-up menu is based on the
4Sight (NeWS) menu class LitePullRightMenu, which is based on LiteMenu,
etc.  This menu substrate has low-level code that uses the binding
of MenuButton for menu selection.  By default, MenuButton is the
right mouse button (look in /usr/NeWS/lib/NeWS/init.ps).
So, as far as I can tell, you can probably rebind MenuButton to be the
left button by changing this.  However, looks like you'd impact all
menus.

Despite my best attempts (and limited time), I can't figure out if
there is a Lite method that can be overriden to solve this.
