SYMPTOM:
When using a panel stack as an information window triggered by a Google Map widget, white space appears around the information window as it is displayed in the Map, in Strategy Web 9.4.1, as shown below:

CAUSE:
This is working as designed, when using Information Windows with the Google Map widget, in Strategy Web 9.4.1. The panel stacks are inserted into the information window that Google Maps generates, this is where the white space is coming from and it cannot be removed or adjusted. A request has been logged to address this issue.
Note: The same does not occur in Strategy Mobile for iOS 9.4.x because it uses Apple maps to display the map.
ACTION:
Strategy will continue to investigate and post updates as soon as they are available.
