Hi Melanie,

I just took a look at the thread you referenced and got a strange feeling of Deja Vu.

Reading the start of the thread I got the feeling I had read it before, then I realised.

Both threads were started by the same person asking exactly the same question (apart from one extra sentence)!

Aside from that, can I ask how you remember what you have typed before and in what thread. I know you are a dab hand with the search function but remembering which of your post is which is a pretty impressive feat!
