Ok found whats wrong. I installed the latest version of google desktop to use it as a desktop search engine. But it messed with opera somehow. Uninstalled and opera works fine.

its xp sp3. I dont use any extensions. Its so weird 31 was working like a charm.

There is nothing on event viewer. I even recreated the crash but there is no entry on application and on system.

I am using opera in all my pcs. I also use opera on an old winxp computer that i have for old games. The thing is after the 31 update i cannot use the browser. It crashes on every page after loading it. It crashes on settings and on bookmarks. Is there smth i can do about it?
