That works great Jim - thanks.

Well, we've done some basic testing
so far.  it looks vaguely reasonable for what we
are probably going to call an experimental
feature - you can turn on incremental and 
play but your structure view and task
list will mess up.  If you want to get back to a
consistent mode of operation - just
do a full build and the task list and view recover.

I don't doubt that incremental compilation
was a hard thing to develop - and if the
incremental structure view is going
to be hard .... I'll wait for Mik to do it :)

cheers,
Andy.
