Well bugger me! (That might be asking for trouble on a site like this!) I never knew you could do that. In fact it doesn't work for me in Internet Explorer, which I normally use, but does in Firefox, but only from another Firefox window and I seem to have got different results from you. All very confusing for an OLDperve. Many thanks trotstride, I'm sure it will be very useful, even if I never get to see Rachel.
