When I open and close the map it always becomes a dramatic zoom in or out in the direction I last scrolled. If it is moderatly zoomed in, and I zoom out by one map unit/scroll on my wheel, when I close then open the map it is now fully zoomed out. When I zoom back in to a comfortable position and close and open the map it becomes zoomed in all the way. This is extremely incoveniant.
Open the map and zoom in a small amount then close and open the map. Now zoom out a bit and close and open the map.
