Hi folks,

Have a file on a public drive which is opened by a number of users using
Alt
Startup Location configured in options. Workbook is hidden, and Open and
BeforeClose events work correctly to create and drop a custom menu. All
fine.

Except when no workbooks are open, the menu isn't disabled in any way. Is
there a way to disable the entire menu or certain items when no other
files
are open?

TIA,

Piers
