John, You were so kind to help me download the virus scan & now this!!! I have printed off and kept all your URL's, they are so helpful. If you were a Parkie I'd nominate you for "Parkie of the year". But for your sake---I'm glad your not! What do you intend to do for an encore?? May you live long and prosper. As Ever, Marjorie Moorefield just another librarian (with PD)
