Martin: 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 .
