@DeborahNicholson I see, when i take your desciption and pull a tab to the right side of the plus, for the first time in a new browser session, the Opera One browser freezes for a split second, even on the newest version, acting like he runs into a memory leak. I've also seen spikes in RAM usage at that moment, but since my system is already running other applications i can't definately say that those are caused by Opera One itself.
