First make sure their group/user has the rights in AppGen. Then you must enable to IRC viewer and check to display annotation toolbar for that user. This can be done by the end user going to their user settings while in WebAX or you can do it from the user profile administrator on the server. If you use the user profile admin they will just log out of WebAX and back in after you make the changes. After that has been checked the next time they go to WebAX and open a document it will ask to install the IRC viewer active x control.
