I know the problem he's talking about. I think. Happens on my Win7 PC as well. When changing the size of the map to smaller-than-the-size-of-the-workspace, the map tends to seek an edge of the workspace to snap to. In other words, a 25x25 grid at 100% fills the workspace and extends beyond on all sides. The same grid at 50% may be located within the workspace, with unused space on all sides (space not filled by the grid), allowing the map to be moved around within the workspace. The same grid, at 70% (for example), is only slightly smaller than the workspace. When it is moved, it tends to try to align itself to one side or another of the workspace's edge, often the side bounding the chat window. In doing so, it seems to move very quickly on its own, seeming to pull itself away from the cursor that is holding it, for want of a better term. In addition, I have seen it seemingly add extra grid lines to fill the space, such that a 25x25 grid may in fact appear as 25x27 in order to align itself. ...is that what you meant, Dieter T? PS: On second thought, I haven't seen this lately, or if I have I haven't been paying attention to it, so that may be fixed. I'm experimented out right now so I'm not gonna go check.
