But you should be able to save the userstate so that the window opens as
the user left it.

It's not necessary you call InsertMenu(after) to actually draw the menu.
The int 'after' is: 0 if it is to be inserted at the end of the menu bar,
a positive number if it is to be inserted among the existing menus, or -1
if it is to be a submenu. This allows, for instance, a menu to be on the
menu bar in one screen and a submenu in another.

Yep, and poking about with Resedit in various apps it seems to more honored
in the breach than the observation.
PS. Jack, Writing this has forced me to look at my bFramework code, and get
the submenus to work, I'll clean it up a bit and send you a copy in the
next few days.
