Ok I'll try some of the suggestions thanks.

In the meantime I have learned a few more LTS basics, and managed to make some sort of amplifier and do basic AC analysis, so that's good.

Where the heck does that come from? Is it a reference to one of Dave's videos, which I've missed, as I don't watch much EEVblog?

No, it is more of an American meme I think (not sure where he got it).  I have heard it for years.  Old curmudgeon hollering at kids playing in his(the curmudgeon's) yard.

All of us old farts are not the same...I am an exception and I see other good-ole farts on this forum too.

The vast majority of GUI based programs use an object-action paradigm,  one select the object e.g. a component or wire) then decides what to do with it (e.g. move, rotate, copy).

I use LTspice HOWEVER...

The GUI is trash because the menu buttons don't scale with screen resolution.  With a 3000x2000 screen even scaled to 300%, the buttons are still virtually invisible.  Buttons like 'Move' are VERY hard to find. There's little contrast and the button is less than 1/8" even on a 27" monitor.  It is almost impossible to use on my 13" Surface Book.

With a 1920x1080 display the program is fine.

Nobody else seems to have this problem.  Probably because they don't size objects in terms of pixels.

So, I use LTspice but only if I am desperate!  It's a great tool but not on my main system. When I'm really desparate, I run it on another machine.

Have you tried right-click running it with any Windoze compatibility options? *not that I'm likely to get a 4k rig anytime soon :(

edit - From my old MCSE debugging days (>20 years back) I recall various dialogue DLL's that are shared by a lot of 'standard' programs. I just Googled 'LTspice windows interface scaling' re: LTspice and found two related links (if one cares to fiddle..)
1) https://designspark.zendesk.com/hc/en-us/articles/214031765-Why-do-the-software-icons-look-so-small-on-my-4K-screen-
2) https://community.spiceworks.com/how_to/137758-4k-dpi-scaling-issues-solved

It could be nothing curable, M$ wants vintage-ware to just go away (even if it is good, and especially if it's free).

It's a continuing line throughout a movie, Gran Torino, from 2008 by Clint Eastwood. He plays a disgruntled hugely prejudiced Korean war vet surrounded by neighbors of the wrong ethnicity which is pretty much anything not white. He is verbally crude and abusive to most everyone, but has a bit of a human streak he is afraid you might see. An old curmudgeon for sure. Good Movie :)
