All sorts of add-on variants of the moving map are available.
But some, indeed only work with FS in windowed mode - On matrox I only fly in Full Screen.
Others require a degree in computing science to add into FSX.
I wonder whether anyone has thought of, or has, added the FS map function into the kneeboard. Like add another icon to the kneeboard that causes the map to run in the kneeboard window - or possibly Google Earth!
If it could be, then the present clumsy arrangement of bringing a flight to a halt while checking the map could be modified.
The kneeboard may be a simple pop-up, but it is a powerful feature of FS. Can it be made more powerful and useful.
I know there are great commercial add-ons like the Electronic Flight Bag but it does not run in Full Screen (as yet).
If someone responds and tells me that there is an already set-up version of this then I will grovel and apologise, and I will pay anyone for the app.
