How to Disable the Preference and About Box Items

[David Burgun]

Hi,

How do I go about disabling the Preferences and the About Box Items?

I am running under MacOS X Tiger and I have the Preferences Item 
defined in the edit menu. I disable the Edit Menu and the items 
contained in it are shown as dimmed, how

However the preferences item that is moved to the Applications Stack 
(yet must be handled in the edit control), is not dimmed.

Thanks a lot and All the Best
Dave
