I recently moved from Opera 12.15 to version 12.17 and I think it was a mistake; which I intend to undo. Essentially my gripe is with the way search engines are now handled. Preferring the better privacy of Ixquick's "Startpage" search window to that of Google's - I customarily set Startpage as the default search engine. With the move to version 12.17, I find this impossible. Currently: every time I open Opera, Google is set as default search engine. You can delete every other search engine in the queue successfully - except for Google that mysteriously re-spawns. Even within a secession (after setting an alternative search engine as default) Google search reappears in each new tab opened. Unsatisfactory...
