enable/disable menu doesn't find the object

[Tiemo Hollmann TB]

Hello,

I have two alternative menubars in my program.

Most times when I am trying to enable or disable menus with:

disable menu "Foo"

I get the error "no such object"

When using explicit:

disable btn "Foo" of grp "Menubar1" of stack "myStack"

the menu gets disabled.

Any ideas, what could cause that the menu isn't found with syntax 1?

Thanks

Tiemo
