Hi Mary, sorry you appear to have trouble viewing the article. The only
thing I can think of is that you are using an older browser

Sorry, I don't understand what you mean by a browser never mind an older
one!

which cannot
handle highly optimised jpeg files, which includes progressive scanning. I
have re-uploaded the article without the progressive scan option.
I would be interested to know if you can now read it ok.

So would I - but there was no url ... :-)

Mary
