Okay, I did eventually find the situation in which the docs are correct. It only took me two days to figure it out. But it is up to the docs to state that situation! This really does carry the notion of coy and allusive (and wrong) to its limit. This is not at all the way docs should be. However, at least my book will be more correct and helpful than the docs, so I suppose I shouldn't complain. m. -- matt neuburg, phd = m...@tidbits.com, <http://www.apeth.net/matt/> A fool + a tool + an autorelease pool = cool!
