Comment #1 on issue 5627 by [hidden email]: "MessageNotUnderstood:  
receiver of "displayWorld" is nil" on clicking the red Menu-Halo.
http://code.google.com/p/pharo/issues/detail?id=5627

I fix it this way:

doMenu: evt with: menuHandle
        "Ask hand to invoke the halo menu for my inner target."

        | menu |
        self obtainHaloForEvent: evt andRemoveAllHandlesBut: nil.
        World displayWorld.
        menu := innerTarget buildHandleMenu: evt hand.
        innerTarget addTitleForHaloMenu: menu.
        menu popUpEvent: evt in: World.

But I cant tell if its the right thing to do.

An expert advise is needed.

http://code.google.com/p/pharo/issues/detail?id=5627

Hi,
Apparently, this bug is fixed on Pharo 2.0, using this:
| menu |
        self obtainHaloForEvent: evt andRemoveAllHandlesBut: nil.
        target world displayWorld.
        menu := innerTarget buildHandleMenu: evt hand.
        innerTarget addTitleForHaloMenu: menu.
        menu popUpEvent: evt in: target world.

There was a fix for 2.0 already... we should add that to 1.4, too
