Before the webinar starts broadcasting, the host will need to ensure that the panellists have permission to share. In the tool bar at the base of the screen (you may need to move your mouse to be able to see it) you will see a share screen button, with a small arrow beside it. Click on the small arrow.

An options box will pop up. Make sure that you have selected All Panellists in both sections.

When you are ready to share, click on the share screen button. If you are sharing a video, you will need to select Share computer sound and optimize Screen Sharing for Video Clip.

Select the screen you would like to share, and click on the share button.
