I had the same problem with the menus since MowAS1 and I didn't change anything compared to the original game skirmish menus. The only way to avoid this issue is to make specials horizontal menus (like in GSM), but i never did it before (I will try to had this possibility for my next missions).. For the Kettenkrad, I used it only as a decorative vehicule, and I will check why it can't go out of the building, even i'm not sure this vehicule is really necessary to win this mission.. ;)

thanks for the reply Bassmaniac,just know that that little glitch does nothing to lessen the mods quality,youve brought a type of "esprit de corps" to the game,its close to the type of mod i'd make if i had your"smarts",thanks again.
