Thanks for the reply. See my sig: 64-bit Win10 Pro, Win Defender, Pumpernickel - I like to keep things simple. The warnings occur in both standard user account and admin account. All other balloons and functions are operating as expected. I converted the new tray tools for use with Pumpernickel and the same behaviour occurred with it too. If I can't figure things out I'll send Florian an email and see what he says.
