	What I would recommend is what I did for my ShutDownSound INIT -
rather than keeping ALL the code in the INIT resource, actually
create two resources - the INIT and another code-type resource (I call
mine PROC).
	This scheme implies that your INIT is simply a loader.  It gets the
other resource, puts it into the system heap and locks it down.  Then it
sets it up with ShutDwnInstall.  The PROC is the actual code that you want
executed at ShutDown time.  Much cleaner and easier...
	If you need some example source, let me know!
