Vortex5 - not sure, probably a coincidence.
I never post on here, but I felt compelled to do so as a result of the idiotic reply from 'overstress' - not sure who rattled his cage, but suffice to say I would expect nothing else from a large amount of the people who post on here. If you are not in the service then I apologise on behalf of those of us who are and are not morons , if you are then I guess you understand where I am coming from.
Hope you find out the answer to your question.
