I think you will find your problem is the fact that you have <!DOCTYPE etc..... on your page.
Whereas in the example it does not have this.
When you have <!DOCTYPE..... it seems to cause the problem you have experienced. Adam should know this as I asked the same thing about a month ago and tracked it down to the doctype.
It is supposed to be fixed in V6.
So Adam when is version 6 due out???? you seem to be ignoring the questions asking!!!!
I would love to see V6......
