I believe there is a service call (Service_Shutdown?) which is issued
when a shutdown occurs. I think one of its parameters is a flag to say
whether it is an 'exit' or a 'shutdown'. I suspect that this call is
only issued after the Wimp and OS have done most of their shutdown
processing.

I'll have a look in my PRMs tonight and flesh out the details for you.

Tom.
