Does your app need more than 4G of virtual memory space? Does your app spend a significant amount of its time splitting huge numbers into 32-bit "chunks" so it can cope with them? If you answered "no" to these questions, don't bother recompiling. It won't help. sherm-- Cocoa programming in Perl: http://camelbones.sourceforge.net Hire me!
