icon duplicated

Just when I thought all was good...
http://www.newlifelincoln.org.uk/contact.asp
Try zooming in or out on the above page...

I know the problem is due to having two Info Windows - one to show when
the page loads and the second for the icon.

The only reason I added the first was because I couldn't find a way to
open the icon window by default.

Any ideas?

Many thanks
