Thanks for the responses
I know it is old software and I have had great value from it - not complaining at all, but no one makes a really good dock for Win 10 and I would love to have one (and would pay)
Adjusting the scaling doesn't help - the dock itself is fine and works a treat, but it is the drawing of the sub icons that is wrong. I guess this would need some updates to the application and I doubt that will happen. Also all the stock icons are looking very dated now, but I have my own so no problem there.
Any other Stardock product which could help?
