It has to do with the Did End on Exit control event; this event, if hooked up, causes the keyboard to be dismissed when the user taps the Return button, *unless* textFieldShouldReturn: stops it by returning NO. That is why, as my book explains, the best way to get automatic dismissal of the keyboard is to hook up Did End on Exit (possibly nil-targeted and uncaught) and either return YES from textFieldShouldReturn: or don't implement it at all. You can get automatic keyboard dismissal with *no code* this way. http://www.apeth.com/iOSBook/ch23.html#_uitextfield m. -- matt neuburg, phd = m...@tidbits.com, <http://www.apeth.net/matt/> A fool + a tool + an autorelease pool = cool!
