The words "which body of code is holding onto an object" don't have any meaning to me, and I don't think they have any meaning to you either. You're just waving your hands. If I wanted to wave my hands I wouldn't be using Instruments. Some specific object did send "retain". It is that specific object's responsibility eventually to send "release". That's how Cocoa memory management works. Instruments *can* know, and *should* tell me, what specific object that is. I wouldn't be here (i.e. using this aspect of Instruments) if this were not the very problem I'm having, i.e. some specific object is not fulfilling its responsibilities and I need to work out who it is. The fact that Instruments doesn't tell me this is not just some mild forgivable accident. It is Teh Suck. m. -- matt neuburg, phd = m...@tidbits.com, <http://www.apeth.net/matt/> A fool + a tool + an autorelease pool = cool!
