Every time I open opera GX on my computer, it loads the window, closes it, then opens it again a few seconds later. Now every time I go to type anything in the search bar it loads it up on google (like I have it set to by default and want it to) then it closes the google page and loads it up on Bing search engine instead. when I click the back button it just deletes the page as if I looked it up on the Bing search engine only.
