Unit skinning dialog gets stuck in BoB

[CapnDarwin]

I ran across the unit skinning dialog with my AA guns and after opening it was blank (no skins for the guns) but there was no way to close the dialog. I needed to exit the game. There needs to be a close button or maybe even a message if no skin exists and not open the dialog.

Other than that, it's a lot of fun. Just need time to finish the fight![:D]
