No, I didn't actually hear anything, but my ears now ache. Must be one of those ring tones I've heard the kids use for use in school - allegedly it's so high pitched that the average teacher can't hear it. Humans tend to lose frequency response in hearing as we get older. It's more pronounced in the upper frequencies. -- Jeffrey Kaplan www.gordol.org The from userid is killfiled Send personal mail to gordol "When I was talking about myself, and when he's talking about myself, all of us are talking about me." - George W.
