Caffeine Has stopped working after latest Mac Catalina update.

Been suing Caffeine for years, now all of a sudden it no longer works after the last catalina update.  The cup still has the wavy lines above it to indicate the app is running and activated, but the screeen goes black even with the screensaver set to never.  Any ideas are appreciated.

I guess you are the on the wrong forum , the caffeine by zhornsoftware is windows only . A search with mac in it will probably return another similar named app for mac .
