Nowadays Opera is not working well.
1-) Sometimes page scroll is not working by using wheel on mouse.
2-) If there was a link in page, when I click it, it opens new tab but the tab shows totaly black screen but if the new tab has any videos or something, it starts. Actually it is working but showing well.
it looks like that: http://i.hizliresim.com/LybgWa.png
3-) Adblock is not working well some pages.
4-) Sometimes Opera says "Opera is crashed" and I don't know why.
