I'm sorry, I still don't understand what are the issues that bother
you.  Are you trying to pop up a menu from the minibuffer, as in the
above x-popup-dialog call?  And all the rest of your questions are
just your attempt to understand why x-popup-dialog doesn't work as you
expected?  Or are you after something else?

IOW, let me be blunt and ask why do you care what are last_mouse_x and
last_mouse_y, and which code sets them?
