I created a map 200x38 with wrap only horixontally. This means that the whole map fits vertically on my screen with room leftover top and bottom from the icecap. IMHO, I should not be able to move the borders of the map beyond the top and bottom but I can. If I press center on a unit, it should center it horizontally and ignore vertical. Essentially the way EDEE works. The way it is it is really wonky!
