Hmmm. I thought I had made a reply earlier but when I came back, there was no post, not just a blank post area!
Nick, I emailed you yesterday about the problem. Did you not receive it?
Anyway, as Christine has said, the blank post problem has happened before (March/Apr) and Anne added
this comment about why it had happened in a Cafe thread "blank post epidemic".
I suspect we have another occurrence of the same, or similar, glitch as somebody else has mentioned it in another forum.
