Frame freezes when I go to another tab when engage is playing

• The preloader itself appears to work without errors
• This problem is occurring on articulates that have been published to Amazon S3
• The problem has occurred on two separate terminals
• Firefox is the test browser

 When the user switches tabs on their internet browser during playback, the slide fails to load the "continue button" . This forces the user to refresh the entire module and start from the beginning, as there are no manual navigation buttons included in the skin

Our module must load and play back without this error, even if the end user chooses to briefly access a different browser tab. Is there a known solution to this?
