1) Desktop (Windows) app, not an online service.

2) Not a system that enables you to write a program and run it. Just
linkable boxes with a text description and flow indicators.

3) Drag and drop of boxes with "elastic" links between them.

4) Inteligent auto arrange. ie you construct the flow with boxes
overlapping, randomly, placed and linked together. Then it will move
'em about into a nice layout with minimal crossing of paths.

5) Decision boxes that have in built with "yes/no" labels on the
outputs.

6) Sub-processes on seperate pages/documents, linked from the parent
(and back).

Smartdraw Flowchart is almost there but only has a 7 day free trail
and fails 3), 4) & 5) but I have a feeling 3) is because I havent
worked out how to do it. The user interface is a little inconsistent
(it changes box shape and breaks links between boxes if you try and
move boxes about) and not 100% intuative but not bad. 6) it does
well.

Pencil and Flowgorithm I didn't get very far with.

possibly a bit overkill for your immediate needs, but perhaps Astah Community edition?

http://astah.net/editions/community

It's a Java app (cross-platform), really for doing UML diagrams. But it
also allows you to draw flowchartsm (and UML 'statechart diagram's, which might
be better for you anyway). I think it has most of your other criteria.
