Yes, I have SL. I have the latest update. I'm simply clicking on the link you've provided. It worked fined for David. So, I'm not sure what's going on for me.
As I mentioned, I'm not worried about it - your tutorial was great and I was able to recreate just fine. I only mentioned it in case someone else was having the same problem, but no one has indicated that they are.
Tx again for sharing. Great idea.
