In the past, when you sent the link to chosen attendees, using the Present Live feature, everybody would have control by default over the slides. The more people you invited to the discussion, the less you could control the slides. authorSTREAM recently released a “control ” button, located next to the right arrows button (>>), which has solved the problem
With this new option, presenters can block or unblock attendee capability to take control of the slides. So invited attendees can be controlled to only be able to use the chat and participate in the discussion without the capability of shifting slides.
