Okay, that's been the suggestion twice now... I've just started
learning cocoa/obj-C, from java (I'm porting over some existing java
code), so I started this project using a closely-related bit of
sample code (Apple's Sketch app), and it seems to use an archived
dictionary to save documents (but maybe I've just misunderstood the
code!). I've just been trying to adapt that to suit my needs, but it
looks like I've hit a wall with that plan! ;-)
