Thanks for the helpful replies. That's more than Opera has done to this point!
It's possible that my OS is not up-to-date, but Windows Updates are controlled by our I.T. department. I am still on Windows10 if that makes any difference.
I am still confused why 109 would work fine, then everything above that does not. Since nothing changed on my end that means that something had to change in the Opera code, or possibly the Chromium base, that is causing this to happen (BTW - I am also running the latest version of Chrome for comparison and it doesn't exhibit this behavior). That is what I am asking Opera to investigate.
I love this browser and have been a user since it's release in 1995 but the recurring problems since the move to Opera One are pushing me toward others. I am trying to stick with it though since it's still the fastest browser out there!
