Google Sheets Problem

I've noticed that if you have caffeine running and a google sheet up, whatever cell you have active will be wiped if left idle for a few minutes.  It seems whatever key is being simulated to keep the PC active is affecting Sheets.  This doesn't seem to be affecting Excel.

Anyone else seen this or know a work-around?

You find the commandline options here :

You can add them to the shortcut for convenience , an example of adding an option to the shorcut is here ;

Thanks.  Exactly what I needed.
