I haven't got Win 10 (just Linux, XP and Win7) so I can't DOMi this one for you, but I'll throw this one in because if it isn't useful to you, then it will be to someone else.BlohoJo wrote:.. I am not regularly at the Windows 10 computer I'm trying to fix.

On Linux, I've seen grown men cry trying to get rid of the dotted 'borders' that appear on focused buttons - they've thrown everything at it. The reason it doesn't work is that those ain't borders, those is - https://www.w3schools.com/css/css_outline.asp
Generally, it's an OS applied thing and I seem to recall it doesn't show up on DOMi (if I sound vague on it, it's because I've just coded it out automatically for years)
It takes outline: none !important; well, but with borders I prefer to DOMi them and see the width and use border: 2px solid transparent !important; etc. there, rather than use none. The reason is that you can bet that some bugger has coded the states borders differently and if you use none then the button or whatever will start jumping around on hover or active.
Anyway, try outline.
