Hello @michaelxxx,
I have checked the page and seen the map display.
[map no_container="true"]<iframe frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="https://www.google.com/maps/d/u/1/embed?mid=1cIT144_LNUCrXibgOrUQjMFtRjZplxiR"></iframe>[/map]
Please understand that the map shortcode, as seen above, is just a container code of the Google Map embed code. It is used to display the map in your post. Take notice that the map embed code is an iframe. Be advised that any contents inside the iframe can only be controlled from the source URL. Any attributes like scrolling are coming from Google. So even if scrolling is set to NO, if Google enables the scrolling all the time, then it will always be turned ON. Take this link for example:
Be aware that Google has removed the ability to turn off the scrolling. Take a look at this developer guide. You can no longer find any reference to the scrolling option.
Hope this explains more about scrolling in the embded code.
