Yes, and then I went searching elsewhere...turns out:
1. I use AVG internet Security for firewall and other protections...including performance management.
2. I reviewed the "fixes" that PC TuneUp had performed and it had "permanently" slept Start 10 as a performance hedge.
3. When I disable the SLEEP, the Start 10 then works from the Start Folder.
So all along it was NOT Stardock's issue, but this could now become a "known Issue" with integration of Start10, W10 and AVG.
Many many thanks for your persistence with this matter Basj - thanks Forum
