I've kind of blogged about this a while back: http://ajwelch.blogspot.com/2007/08/when-b-and-b-both-return-true.html ...but it still always catches me out. The rule I mention there is "never use != where both sides are sequences of more than one item" which is why I thought ". != x" would be ok... but it looks like that should be: "never use != where one side is a sequence of more than one item" -- Andrew Welch http://andrewjwelch.com Kernow: http://kernowforsaxon.sf.net/
