I have a Excel Document that contain many macros and it was protected.
I unprotected the doucment and deleted all macros but when I tried to delete
a Custom command from FILE MENU under customize/rearrange commands, I would
not see the custom Command under File Menu .. good, this is what I expect.

but after I save the document and reopen the document again, The same Custom
command show up again under File Menu in the same position as If it was
never deleted!!!

Any Help would be appreciated.
