I Can Hear Audio but I Can't See the Presentation
If you are hearing the audio of your session through your computer speakers but cannot see the presentation, the GoToMeeting, GoToWebinar or GoToTraining viewer is likely minimized.
You are joined into the session but the viewer window is hiding behind another open window or application.
Check the Task Bar or Dock for an orange, blue or purple daisy icon. (Clicking this icon will expand the viewer allowing you to view the presentation).
