Damn it this has been pissing me for the last 1000 years! It's the reason I enabled ad block again! When playing a flash video sometimes the ad won't load, or it decides to have common curtsey and not show itself and block the entire screen (of the animation).
However when it does that, the moment I click "play" both the video AND the ad play at the same time! I don't see the ad, I hear the audio. It forces me to refresh the page, however it unavoidable when replaying a video. Every single damn time, the audio has to just.....URGH! Fix it bro! Please.
