Hi Thomas,
No, it is not possible to grey out a DIAdem menu item, but it is possible to rename it, change what happens when you select it, or make it dissappear and reappear at will-- but all this can only happen through VBScript commands. All the pertinent commands start with "MenuItem...()"
Let us know if you need more info,
