So, I upgraded from 11.x to 12.00 and then to 12.01 on my Mac laptop running Lion 10.7.4. Prior to the upgrade when I hit the Home button, it would take me there in that current tab. The same thing with the search bar, if I typed something into that and hit enter, it would display results in that tab. Since the 12 upgrade, doing either of those opens a new tab with the home page or search results rather than keeping that activity in the current tab. This is becoming an annoyance. I have searched the about:config (Opera calls it Opera:config) and could not find anything about that. I have tried to replicate the problem in Opera 12.00 in Windows 7 and could not. Any ideas on where to look for a 'setting' for this, or perhaps a config file that I can delete? I'll wait a bit and see if I get any responses. Just as I was typing this I remembered OS X has .plist files which are preferences, so I can try to delete that and see if it fixes it, but I'll likely lose some other things I'd like to keep. So if there was a setting I'm overlooking that would be ideal.
