I have Opera 44.0 on a 2102 Airbook. On many sites it does not work! Much worse than even Safari. Sites don't fully load, formatting of pages messed up, hotlinks and buttons don't work. Is this just "the way it is"?

I recently downloaded Opera on my AirBook. Have version 44.0.2510.857 Every couple days it completely crashes, just closes without warning. Any suggestions greatly appreciated.
