Okay. I cant quite get it accurate, seeing as the measurement settings for screen width and height don't do decimals, but i've gotten it to where the offset is at least relatively small (my moniters height measures out to 255.77mm) and if the offset becomes serious, i'll just have to take it into gimp and adjust it until it does fit. However, one other problem I've come across is the fact that viewingdale layers things relative to the size of the object. A smaller object always overlays one which is larger. Is there a way to manually adjust the order things are layered on the map, so i can have (for instance) my corner keeps tower actually appear over the corner keep, without having to resize the cobble tile to ridiculous proportions?
