Well, it appeared to work, unlike all the others it showed an image of the ND555 before I posted, but now after posting it is not visible, just an empty outline
this has been another frustrating waste of time. I think I shall stick to not bothering trying to post images.
IB It sounded from earlier post you had cracked it by just having the image displayed -click enough times. A picture paints a 1000 words.
