its a bloody travel site, mine is doing this too.

oops stopped now?...dont know why and WAS definatly hitting POST ?? even did it when i hit preveiw post?

Hi - we think this might be a problem with one of the creatives being used by our agency and we've contacted them about it so hopefully they'll put an end to it pronto - do let us know if it appears again and sorry for the irritation.

hasnt happend since this afty, but will do
