I can't change my default search engine to google or bing. I don't know how but my wife has yandex.ru as default search engine and I can't change it to google or bing. I reset opera browser to default settings, I had google for few days and then yandex is default again and google is completely removed from opera browser. How can I prevent yandex to do it?

@sgunhouse That is weird. I am tousands of kilometers far from it. I will check. Thank you.

@leocg Yes, I've checked again all settings and reset default settings helps only until restarting Opera.

@leocg I need to add google search manually and it is not possible to make it default. Only wikipedia and yandex.ru can be default. I can only restore Opera to default settings and after few days I have same problem. I am not sure how it is possible because I have slovak location and language.
