Thank you so much for the great software you have. I have a similar issue, some of my icons (Logitech damimg Software, which is important for me) in the notification area do not show anymore when I start my computer. I downgraded to the stable version of DF 7.3.4 and it came back. Hope you can fix it.

I have windows 7 ultimate.(I downgraded from 10, I could not update to the latest service pack)
