Admin Access Control to Plugin

Hi

We have installed the plugin and it works well - however we are an admin and can access it and our client is an editor. When they login to the admin area they can't see the Popup Pro plugin from the menu to add and deactivate a plugin.

We don't want to give them access as an administrator as they will likely change a lot of settings.

Can you advise what to do? Do you have a plugin to provide access controls or something or advise code wise what to do as we really need them to access it as an editor.

Thanks

Olly
