Why does Presenter refresh after a certain period of inactivity?

It can happen that a loader suddenly appears in Presenter and then you end up on a blank canvas. Unsaved data is lost. The Chrome browser 'discards' the inactive tabs after a period of time. 
The tabs that qualify for this are often heavy and inactive for some time. For normal web pages this is not a problem, but for Presenter it is! 

 

  • Unsaved content is lost
  • Waiting time during 'refreshing' the screen

 

Possible solution for the user: 
Download the Chrome Extension that blocks the automatic discard:
