As for GIMP, I'm not quite sure I know what you mean.
Ha! Yeah, when I was writing that bit I was thinking "does this actually make any sense?"

I don't know the correct terminology, which makes explanation difficult. If I was at my computer I could take screenshots, but as it stands I'll try to muddle through with words.

If you use the rectangle select tool to select a whole strip down the side of the map and cut it, then invert the selection you end up with a rectangular selection encompassing the rest of the map. You then use the Move tool to drag this to the right, all the way to the right hand edge. At this stage if I Select None I still find there is a broken yellow line down what had been the left border of the selection. It's no longer at the edge of the canvas, but I can't get GIMP to draw anything to the left of this line.

Does that make sense? If not I could take some screenshots tomorrow.
