Zoho Meeting locks up often

Zoho Meeting locks up often


We have been using Zoho meeting for the past couple of months. Weekly we have an on line meeting for about 15-16 people. We usually show a powerpoint or other presentation and somewhere midway through the system locks up. The screen that everyone else is viewing freezes and the only way to get it undone is for everyone to log off, including the presenter and then log back on. This happens in every meeting.
