OK, George, you win. Let me also apologize for having a short fuse yesterday. I have spent the last two days with Vivian at both an ophthalmologist and urgent care, as she has come down with a nasty case of shingles that have caused the pathways along her cranial nerves to swell to the point that her left eye was swollen shut, with weeping blisters on her eyelid, not to mention what the whole left side of her face looks like. Sorry to have gone off like that; stress does strange things to a person. Ron
