Thanks jmh. I've saved it and will study it in great detail in the next couple of days, but it does seem to offer a solution. Noticed you are in Copenhagen - did my bit to support the Danish economy at lunch time today, ate in my village bistro. The Chef is Danish and his Belgian wife does the rest. Had his starter of Herrings prepared in 3 different ways, believe it or not a very popular starter (even with the French) . . On the 18th he is doing his annual Danish meal a sell out as usual.
