No there are no Google Maps on the page. I tested it on the index page of 3 of my websites. None have Google Maps on them.
1. corporatecats.com.au
I get the JavaScript error message and then Dreamweaver stops responding.
2. primetimemeats.com.au
I don't get the JavaScript error but Dreamweaver stops responding. It seems to be while trying to display the preview.
3. firthwebworks.com.au
Same as 2 above.
My pleasure, it looks like it's going to be a great extension, when I finaly get it to run correctly, I struggle a little with colour selection so it will help me immensely.
