I think you're saying that mouse-1 on an Imenu menu item does not take you to
the right place (or anywhere at all), whenever the menu is hierarchical (i.e.,
has submenus).

FWIW, I do not see that problem in any GNU Emacs version (20-24) on MS Windows.
Consider filing a bug report, giving a step-by-step recipe that starts from
`emacs -Q'.
