I go on a few sites that have videos or games, and something like this happens to them:

That white box is going straight through the video. I'm not sure if it's the site or my computer, but it happens all the time.

Might have something to do with your Flash player. Are you sure it's up to date?

Not sure at all, but would it inform me if it needed updating?

The most recent release was 2 weeks ago, so I'm not entirely sure.

The only things I can say are update Adobe Flash player and try a different browser to see if the problem still occurs.

I'd recommend re-installing your browser before trying a different one.

Its a really horribly put together site, its probably that the set up doesn't account for the size of the video player.

That's what I would've thought except he says it also happens to other sites too

It's not the same exact problem, but very similar. It has a box in the bottom right of the game on the site and when I scroll up, the box itself seems to move as well, covering up more of the game screen.

What other sites have you seen this on? It seems that this could be an advert covering the area on the screen.

It's a porn site, so yeah. :/

Well there's your answer

You mean, problem.

Dude lay off the porno websites. They're riddled with viruses.

Their riddled with viruses if you don't know how to use the internet.
