Ok, I found it.. it was a simple case of not
waking things up if an orderly shutdown happened.. opps.
A comm lost (where you had an abort or some non-orderly
shutdown) would have worked :-D
I will add this to my next patch.. which i am due to
submit.. I will send and let George have a look.. so
I should get it in before the end of the week.
If you want a private patch let me know and I will send it .
