I have found that I can no longer watch YouTube video's. All I get is a black screen, so no visuals but audio is not effected. This does not happen when I use Opera or Firefox for instance. This only happens when I use Chrome.

I am using the Stable version at the moment. I am wondering whether changing to Beta will sort this out, or do I have to wait for the next stable update?

Any advise is greatly appreciated.

Well, I've just worked out why this happened all by myself. Thank you for all your advice and suggestions.
