Here's the trick with the Carb info panel...
If you are looking at the Skada Panel (just an example), and you hit M. Carbonite's maximized map will open. You hit M again to minimize it. It will minimize, but it will cover the Active Infopanel, in this example, that panel would be Skada. So you would end up looking at the Skada Infopanel, with a nice Carbonite Overlay, lol.
Very easy fix when/if this happens though, just cycle the info panel windows till you get to Carb's, the Carb map will be missing from it, Hit M to maximize, then M again to minimize and the Carb map gets re anchored.
Stupid, simple, and slightly annoying, but hey, it works
