"Bug" means, roughly, "something that should be fixed" not just any "thing that has some unwanted consequences". So yes, by calling it a bug you are asking and implying just that. If you don't mean that, don't use the word "bug". -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco
