This is due to a hierarchy problem. In fact the Tk toolkits imposes that a
menu
MUST be a decendant of its menu button (otherwise mouse events are not
propagated to it). Consequently, youll have to modify the menu creation with
   (make <Menu> :parent bar-colors).

The following line you provide permit to associate the menu to its menu
button. This is no more necessary in 2.1.3 since this is done automatically
when you specify a parent to a menu (and thta this parent is a menu button).


This problem doesn't arose in the STk code since you define your menu
with the name ".bar.colors.m" which is a son of the menu button ".bar.colors"
