Perfect.

Its already set to =true.

Now I have the engine choice but when I select Opera, close the browser, and reopen it MicroB is still selected. Anyone having the same problem?

And another possible quirk that i noticed is the browser wouldn't obey my disabled Open Thumb pad with Rocker option. I would click up and down the page element and it would open the small keyboard when it ran into a textbox. I use the past tense because it doesn't do it anymore.
