This has nothing to do with the "Return" key on the keypad - it has to do with the text field resigning its first responder status. The "Return" key invokes textFieldShouldReturn: and does *not* automatically resign first responder (unless you've implemented Did End on Exit). As usual, I suggest you make a teeny little test project, completely clean, consisting of just a text field and its delegate, so as to prove to yourself that textFieldShouldEndEditing: is in fact called. m. -- matt neuburg, phd = m...@tidbits.com, <http://www.apeth.net/matt/> A fool + a tool + an autorelease pool = cool!
