GS Scheduler does not upload listings unless "screen is left on" on iMac

Solution presented here works:

BUT leaving computer unprotected without password is NOT a solution.

GS 7 (which I was using absolutely without ANY problem at all till last week) had NO PROBLEMS to function when screen was password protected. I don’t understand why the same functionality / solution can’t implement in GS9?

The workaround presented above is just that - a half baked workaround. Not a solution.

Leaving any computer un-protected for days when I am travelling but have auctions scheduled is not an acceptable solution when asking us to pay a monthly fee.
