Hi Bob,
I have finally implemented your suggestion. I created an unique undoManager
which I assigned to every window by overriding windowWillReturnUndoManager.
The undo works well, on all the windows, but it cannot register the
setActionName.

    [[[self undoManager] prepareWithInvocationTarget:anObj]
        SetValues:[anObj GetValues]];
    [[self undoManager] setActionName:@"Move Object"];

I see only "Undo" in the menu item. Instead when I don't override
windowWillReturnUndoManager, I see the right action name "Move Object".
Do you know how to fix it?


Best Regards
