Hi Christopher, Firstly, thank you very much for confirming the issue - I'm glad to hear I'm not the only one to have hit it! Secondly, unfortunately it seems that your diff got lost in the aether. Could you please post it somewhere, or send it to me directly and I'll put it up somewhere? I'm eager to see what the solution is.
