Thanks arthur , makes the game playable for me now , need to get some practice in.
Gypsy see here for installing jgsme for BOX. I downloaded the file and put it into my battle of stalingrad main folder, there is a pdf guide in the download with instructions. I prefered a seperate install for il246 and BOX
