I think I have solved my problem. Hovering over the taskbar button, I noticed is brought up "Opera 30" ( I have 41 installed). So I opened Opera via Programs, and now my external links work!
Doesn't explain why this button has been working from opera 30 up to now and why it has suddenly decided to stop, but if I can get it to work...

Me too.

Opera turbo enabled. VPN not enabled. I can get my web email, but nothing else. I've seen somewhere that I should click "forgotten Password" and reset it, but I cannot find this option.

I've has this problem for about 2 weeks now. I can still access the www via Explorer on the same PC, so connection is not the problem.

Thanks in advance for any help.
