There has been a problem here, that forced me to remove id of the dialog. The problem was the id is supposed to be unique, which was not the case and when both downloads and downloads2 paragraphs were on the same page, it caused the first one not to work at all.
This is now fixed, however the styles of the popup dialogue are supposed to use #dialog as the selector, but that is no more possible. Try the first and the last download paragraph and you will see the difference.
We need to find another way to apply the styles.
