Sure, I understand that. We bridge builders are a very small audience - I'm under no illusions that Apple put in that kind of effort just for us.

I don't think you could have hit that target more squarely even if it had been. sherm-- -- Cocoa programming in Perl: http://camelbones.sourceforge.net _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
