The pictures even switch, when I use the scrollwheel of my Logitech "MX510" mouse.
What distro do you use? Maybe it it a distro or desktop manager issue?
What is more important than features, IMO, is security. If Opera for Windows is already at version 22, while Opera for Linux is only still at version 12, does that mean that Opera at my Linux install is less secure than Opera-for-Windows?
That is the questions that matters: how insecure is Opera 12-for-Linux compared to Opera 22-for-Windows?
(This being said - and, no offense, dear Opera devs - I use Firefox before Opera, because I see no reason to switch to Opera. But this being said too, I can please the Opera devs by saying that on my (older) Android smartphone, I have Opera Mini installed, and it works quite nicely.).
