I have just installed YAWL 4.1 on a Dell XPS-15 machine running Windows 10. This machine has a 3000 x1800 pixel screen (about the same as a modern Mac). The console runs but renders in unreadably tiny fonts, no doubt based on physical pixel calculation rather than logical point sizes. Presumably because the hidef screen is the primary one on the machine, even when the console window is moved to the older second screen (1400/1000) it retains the original unreadable fonts.
I've uploaded a screenshot showing the console next to the window in which I wrote this message, to give an idea.
This must be a very common problem - is there a build or other fix for it?
