@burnout426 Thanks for your reply but I found the solution myself. You got this starter page thing that you want people to jump through. I would just close that tab down. But Opera will not operate properly if you don't jump through the hoops first. Backgrounds will not show, logo keeps showing up. A skip button for people who already have Opera would have been nice.
What is the email service provider? Does it provide the option to switch email account (like Google does) or you need to logout and then login for another?
thank you for your advices, comments and reports regarding the mentioned issue! It helped me to understand, that I am not the only one having the problem.
Thank You, also to the Opera Team for fixing the bug!!
