Thankyou IBobi for this most useful tip, it's brilliant. Can anyone please help with my next problem? I have successfully taken a screenshot but each time I try to use the icon above to add the picture to this message it asks me for a url no. I am on an iPad and can't see one anywhere. Is it not possible to simply upload the image somehow?

.... Reads WIKI and returns 10 minutes later ... Actually, I can save you all the trouble - I have now read the WIKI on this (what and where is the 'clipboard?!) and am going to retire to a dark room with a wet towel around my head and see what I can figure out. This is all soooo last century - why on earth can we not just upload?
