MDI View with Multiple Menus

I have an MDI application in which the menu is getting very complicated and is going to get a lot worse if I do not find a solution. A simple solution would be to have several menus. Displaying the one applicable to the task currently being worked (or the state the view is in).
My question is how to manage multiple menus attached to a MDI View. I do not want to alter the Doc template as it is the correct menu to start with. The following code works if a single window exists or if the views overlap. It fails when multiple views are tiled.

Any comments as to why?

Also it does not work if I do not set the menu in the views OnDraw function.
This I am confused with as why can I not set the menu based on the active menu
for the view that is being selected (see the OnActivateView function). But the pointer to the view being selected is obvioulsy correct due to the BOOLean flag is correctly selected.

Any comments? Thanks
