We have Sugar Open source version 4.2.lb. The e-mail links don't work in the Detail View of the Leads Module and in the Acccounts Module. They do work in the List view of the Leads and Contacts Module however. The message we get when we click on the e-mail links that don't work is: "Warning You do not have permission to access this module."

Can anyone suggest what the problem might be - or at least where to begin investigating? (We're not computer programmers so would appreciate plain language in any responses we receive to this posting. )
