This is a very common (and unfortunate) line of thinking: "I prefer bugs that I know rather than (fewer) bugs that I don't know". Although there is some sense in it, this is just pushing too far. Be assured that *lots* of bugs have been fixed since 3.15p, and if new ones have been introduced, they are certainly in very complicated and unlikely cases, since the latest versions of Gnat are routinely used for demanding and critical software - or you can have bugs in the recent 2005 features, but you are certainly not using them. Why did I climb on my soapbox? Because I see constantly people asserting the risk of making a change, without asserting the risk of *not* making the change. Note that most of the free software community takes the opposite view (always use the latest version) and it does not work so bad... -- --------------------------------------------------------- J-P.
