Nick,
I have a "beautiful" Flat Screen Sony, it was a Christmas gift from a dear lady friend. Back when LCD flat Screen Monttors were $250+. I was living in New England and left there 14 years ago. It keeps playing. It is 4:3 screen format.. I use it with a 4 port KVM in the hamshack. (Win Server, Win 7, Linux Mint, Win 10)
The calibration box on Win 7 on that 4:3 screen does exceed the screen size, but I can "drag" it around. at pop-up 75% is visable, So I'm ahead of you, as far as my GUI... My graphs are not perfectly formatted to my screen, perhaps better looking on a widescreen.
I hope the author places this on his "Honey do list" but More important is the "real" nuts and bolts of VNA that we so appreciate of the program to date.. I can click and drag just fine..
I also appreciate multi platform versions the author is working with.. goes beyond my pay grade indeed.
