Sorry, I should have known better. I apologise for sending my posting, but I got a phone call, was distracted for a while, and did not update my mailbox before finishing my post and sending it on. I hadn't seen your message, Julia, until after sending mine. I couldn't unsend it, then. Pat Cross Davis - Texas patdmom@aol.com Burke, Callis, Carrothers, Cross, Martin, Paul, Warren, Wolfe, Word
