Magic constants like this are evil and are a serious indicator of poor programming practice. A computer with a faster or slower processor, or the same computer with more or fewer tasks going at once, can make your "working" code suddenly fail. Then you're back where you started. Please describe your problem in more detail so we may help you fix it the correct way. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
