flippin eck!! thats done the trick thanks francat, kjtrek and zardoz. I wish had discovered this a lot earlier. ive lost no end of posts that i had written but failed to get posted. i belong to a couple of other forums and ive never seen this on them.
i wish this 'remeber me' thing had been highlighted as an important issue some where on the front page as im sure im not the only one thats had these issues.
thanks so much guys. i feel a right wally now though!!!
