As for how they figured out what the problem was...it's not quite as random as it seems. They know what they "fixed," so they have a pretty good idea what they broke. :-) [rant mode engaged] Which is precisely why they need to do SERIOUS QA testing before releasing these SRs. I would bet they are not regression testing it at all. That is to say they don't test the entire codebase once making a fairly impacting change (as with the shadows). If they had regression tested they would have noticed the new bug before it was ever released. As a software developer myself I cannot believe the number of bugs and problems they let go out the door. And we're talking about SRs here that are supposed to FIX things, not break 'em... [rant mode disengaged] ah, I feel better. Code I write goes through extensive testing at least :-) -gz-
