Hi Den, I was investigating it and had a long reply typed out but I didn't want to bore you to tears with my badly written novel. I'll send it shortly. I couldn't reproduce the problem and I can't see how the behavior you are seeing is possible, so I am concerned about the root cause of what's wrong. I will accept the hotfix before 2.12-rc0 or 2.11.1, but I want to try and see what's going wrong in the meantime.
