I already reported the problem to opera, as I said above. Thanks for your attempts to fix the thing. As I said, I have been using Opera for many years and still love it, but the support of Opera is not accessible enough and should be better. There should be a way to get in touch with them, not just a ticket and then hoping that they may or may not read it. I hope that they are on it now and provide an update. I report here, as soon as there is a an update that fixed it.
