VBA Excel project won't work when opened in intranet
 

I have a Excel VBA project.
We are giving access to the user throuh intranet.
Combo boxes, and all other features are working except popup menu
I have a popup menu (temporary) which is created if not existed and pops up
on right click. It is not working. I can't acess the code as the file is
opened in intranet (int explorer).

This works perfectlhy when we open the file directly.
How do I see the problem, how access the code?

Thanks the help.
