I have developed an application with custom toolbars. At the end of my
toolbar Excel adds a drop down 'Tool Bar Option' that lets the user customize
the toolbars. Whilst I have set my custom bar option to no customise, the
user can still create a new toolbar and add their own controls!

Is it possible to disable this drop down or is there some other way to
prevent the user from accessing the customize toolbar options?

Many thanks
