Don't worry about it, it's an updating of the site thing, initiated by the owners and we are all suffering from it... There is a way to avoid the double post, I accept you should not have to do it but it is a work around until Mick the owner fixes the problem. When opening your browser open two tabs. When you post and it comes up with the do you want to leave message, which is indication that it is going to double post, go immediately to your open second tab and view not606 to see if it has already posted. Chances are it has. Then just close the first tab. Problem sorted. Crazy eh? If you can be bothered with this just carry on, myself I'll wait till it's corrected by the owner....
I wasn't jus getting double posts some of the posts were missing half of what I had typed was doing my box in
