This problem has seriously plagued Opera since the god damn dark ages (big ads at the top of the browser) I don't know what causes it, its a problem that I have also seen in other browsers but usually not at the same time. Never found out what actually can fix it, and I know clearing your cashe/history or restarting the application or reloading the page doesn't fix it either so whats up..
Biggest issue is its intermittent, usually doesn't effect all browsers at the same time and it effects only some web pages(usually high profile sites such as known forum software ie IPB, facebook, youtube and google searches). also its not a host problem..
Opera version: 35.0.2066.37
Windows 7 home
and just as I wrote this it started working and wasn't able to get a damn screenshot because I could have swore I have 90 of these damn things but apparently not! when it happens again ill make sure to post images here, in the mean time feel free to suggest what might be causing it because I have no damn clue.
I WANT MY PESTO BACK..
