When I click start engine in the right rail of the application, an alert is displayed behind the Google Earth frame of the Harvard Yard.

I cannot click on any items that are displayed on this alert, so I cannot drive the vehicle.

This is while testing an unmodified version of the application's JavaScript.

I am using a Windows 7 machine with plenty of resources.

How can I make the alert display in front so I can click on it and drive the vehicle?

  • I tried loading the plugin in IE11 and FF33.1. The plugin will not install or load in either browser. Commented Dec 15, 2014 at 18:05

Use the CSS property z-index. The higher the value, the more front it displays. By default, Google maps has a high z-index. You can either reduce the z-index of the map or increase that of the alert.
