Well Everhelpful I do have IE7 so it could be that I suppose. There again I havent noticed if its the same on Mozilla. I'll keep an eye on that.
No squarebear I havent got Norton. Ive heard its rubbish.
Ah Ethel you may well be right. I sometimes dont sign in if Im just quickly scanning through. Once again I havent noticed if it happens at these times (turns red and draws circles with toe).
Thanks all for the advice, I'll watch what Im doing and let you know.
