Problem with menu bar

[Maria Joao]

I have an access database and I created a menu bar.

Suddenly, the contents of some parts of this bar desapeared. Only shows an
empty grey box.
On the other hand, when I try to open the same file in another computer, the
bar is still there all complete.

I need to send this file to some clients and I don't know how it is going to
be on their computer.

Can anyone explain me what is happening here?

Thanks

Maria Joao
