NSTextField is not (documented to be) KVO-compliant. Don't try observing it. Instead, turn on the isContinuous property of your text fields (the "Continuous" checkbox under the State group on the Properties inspector). That'll send the text field's action on each keypress. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
