Seems that ED has add the function to each plane to click and pull on the canopy cover under the "Ctrl+C" mode to open the canopy.
Although it's a convenient setting, some collision happens. No matter if i choose the "Ctrl+c" mode for the censor, when i change to F10 to watch the map, click and pull the map, the canopy will automatically open or close itself.
This doesn't matter much when on the ground but will cause the lost of canopy cover when flying, hopping for a solution.
