No, you really can't. A backBarButton item should have a nil select and target, allowing it to perform its standard function, namely to go back. However, you can perform other trickery that allows you to customize what happens at that moment. You can change beforehand what the user will go back *to*, and you can hear through a notification when the user does go back. Any further advice would depend upon your explaining what you are really trying to accomplish. m. -- matt neuburg, phd = m...@tidbits.com, <http://www.apeth.net/matt/> A fool + a tool + an autorelease pool = cool!
