Thanks Mike. That makes sense - a bit like a lawn goes brown in the dry weather but doesn't actually die (unless you are very unlucky).

And here is another perfect example of how Remy and I quite often 'ninja' each other in responding to questions ?

Thanks Shessar! Yay to Ralf too, who had the headache of sorting out one of the most disorganised annuals I've ever not really prepared all that well!

You shouldn't type so fast Quenten! :P
