I tried Americas, Europe and Asia - none of them work. From Western Australia.

Is it me or is this a general situation?

I've used Opera for years and years. My previous computer died so I got a new motherboard, Windows 11 Pro etc and setup Opera again about 8 months ago. Ever since then I get two windows when I fire up Opera.
I also use Firefox and had the same problem there too. But, with help from an AI, I unset a few options etc and Firefox came good - only one window.
Even with help from the AI I cannot get Opera to stop opening the second window. I've tried setting and unsetting virtually every option but, every time I fire up Opera, up pops the second window. I've asked the AI but nothing works....
Anybody know the secret? I've tried everything so, please, don't suggest the obvious hints.
Thanks in anticipation

I added a filter but popups to the address still popup....
