Resolved

Once again, I got the early dog walk, and before the weather got really windy! For a change I followed the main drive in the Estate rather than the woodland that runs parallel, affording myself this fine view of Knightslaw Tower that is a feature of the planned landscape.

Back home, I got to the bottom of some odd behaviour in a major piece of code at the heart of the solver we are developing, and now have an interesting bit of program development to enjoy.
