Let me tell you about a "theory" of mine - the theory of "bug time." I know this sounds silly, but I have a great deal of empirical evidence that suggests that bugs lie dormant in code; perhaps for dozens of years... then, suddenly; they'll begin manifesting themselves. When you begin investigating the problem - the answer it usually readily found; the developer frequently lameting "This never could have worked!" I think there could be sound psychological reasons for this - such as people not reporting problems, etc.... but I don't have any physical reasons to bring logic to my observations :-) Anyway, following the theory of "bug time" - you should see a few more reports like mine begin to trickle in :-) :-) - Dave Rivers -
