I have a custom popup menu on the Worksheet Menu Bar on which I would
like to make particular buttons unavailable in certain circumstances.

Rather than setting their enabled property to false (and having them
disappear, which I think would confuse users), I would prefer to have
them there all the time but greyed out in those certain circumstances.

Can this be done? Or is greying out available only to Excels' built in
menus?

Suggestions appreciated
