Well, three months later, and a new update, so I tried again, this time with Version 73. It opened nicely but within two or three minutes it froze, Activity Monitor showed once again, it "was not responding" and had run up 100% of my CPU. What is the deal? Why can't Opera work? I'm on an iMac with 64 Gigs of RAM, running 10.14.6, and Opera will not work at all!
