Are you really a mathematician who can solve problems on his own as they arise or are you just Mr. "Linux does this better for me ..."-whining-basher ? I don't give any explanation nor solution to your whining-problem since Dave Bodenstab already did (btw his reply to you was excellent and let's you look like a little pussy).
