@stevenjcee Well, I re-installed the most updated Catalina, to see if it might fix a few bugs. Even tried opening Opera again (ver.75), but once again, within five minutes, it ran up about 100% of CPU Usage, and became "non-responsive" requiring a force quit!
What is happening??? I've got plenty of RAM, a very fast connection, fresh OS, every other browser works just fine, all except Opera, which I used to use, and would like to get back to using, but it has been impossible to do. Does anyone have the slightest clue as to what is going on, and/or what I can try to see if it might work once again?
