This isn’t related to Opera at all, but a warning.
MemTurbo support requires you receive unsolicited email, and then dismisses user complant. This all caught me by surprise, but after a week of waiting for a response, I have heard nothing.
Oh, and I can relate this to Opera somewhat: I paid $30 for MemTurbo, and I’m pretty sure I paid to upgrade from 1.x to 2.x. Rest assured I won’t be paying to upgrade any further.
