@donq Thanks for the insight. But, since this is two completely different computers, and two completely different operating systems, one of which I have no control over (it is a domain install on a work laptop) I cannot wrap my brain around that it is under another user account. I mean, if you read this thread in its entirety, and get past all the circular logic present, having another user account for Opera would probably be within the same realm of possibility as having the sound turn on for me, but not in My profile. After many hours of curiosity gave way to frustration, which led to apathy, I won't be pursuing this any longer. Having pored through the entirety of the windoze operation system within the limits of my knowledge (which is quite a lot) I just don't see it. The software is all installed in my account, in my OS, and so on. My work computer has no additional user accounts, I got it new. It doesn't even have an active Admin account (although it is present if needed by IT). Of Opera has another user, then there is obviously something very wrong in how it's written, and this sort of rogue behavior isn't welcome on my computer.
Pardon me for saying but this thread is going off into the twilight zone, and it's as though I will ultimately end up having to fix the source code or something completely wasteful like that.
I once was a car enthusiast. When one owns a car, replacing a starter, tires, brakes, its all part of it. If you like the car, replacing the motor or transmission is a possibility. However, I have yet to have a car I loved so much that when someone torches it and it burns the the ground, that I'll fix it. It's just how I feel.
But I did come up with a solution, it's working really well so far.
I uninstalled opera completely from both systems and installed Vivaldi and Firefox as alternates. Firefox was abandoned about 2018 by my last university, and in my own experience it completely stopped working properly at that time. However, maybe the Netscape genes will resurface and it will be good. In the meantime, Vivaldi is quite good, I had forgotten about it until I looked up browser options. I could care less about the finer points of the whole internet experience, but I need to have internet access for my work, and things that I do. When I cannot use a Swedish keyboard, have sound, and a host of other small "issues" it's time to set that burning carcass to the side and start anew.
On a side note, when I clicked on the link in my email, it opened up this thread in MSIE and wow, talk about a terrible browser! Buttons didn't work, script didn't work, It's been a while since I've use it, and I never use it intentionally, now I recall why.
Have a great rest of the week.
And.... after some inactivity, this will be marked "solved" I know it.
