People write extensions for Opera, some of them provide new gestures... There must be possibility to turn off default ones...

I meant just dissable functions that Opera provides for these buttons (button 4 = undo page, button 5 = forward page). Is it possible to dissable all gestacures? I think that could solve my problem.

Hi. Is it possible to remove functions from mouse buttons 4 and 5?
I use my own scripts for these buttons, and every time I click them Opera changes site which is super annoying. Help me please
