Heh - indeed. I'm not averse to writing code 8).. I just thought there 
might be a way to do it just using IB and bindings.

Yes - I have subclasses NSArrayCotroller and given it an IBOutlet to 
the NSTextField etc. Works a treat.

There do seem to be an awful lot of ways to accomplish what you want 
in Obj-C and Cocoa. I've been writing C/C++ for a living 15+ years, 
and the weaker type constraints and generally more flexible 
architecture of Cocoa are taking a little getting used to. Most of the 
external libraries that I use in my day job are very strict in how 
they allow you to accomplish a certain task - Cocoa feels a lot 
different. It *is* falling into place as I try more things, but one of 
my worries is that I pick up too many bad habits and adopt techniques 
that may be frowned upon by more experienced Cocoa programmers.

Thanks for your patience - it is most appreciated.
