Several issues I've been facing

First off, I love products from Zoho. Well most of them. I've recently been using Zoho Meeting but have been a little disappointed in it. Here are my issues:
    1. Attendees often complain that the join button is greyed out. Initially I thought perhaps they try to join meetings that haven't started yet, but that is not the case

    2. When they are able to join, they can only see part of my desktop. Does this have to do with my screen resolution? Is there an optimal screen resolution for the presenter?

    3. Yesterday I wanted to make someone else the presenter, but when I pressed the "Make presenter" button, the meeting abruptly ended. This happened twice



If it helps with debugging, attendees mainly choose Flash viewer.
