When an object is being drawn (i.e. not editing an existing object), dragging the mouse past the edge of the draw window while the left mouse button is being held down, will cause the draw window to scroll in the opposite direction so that it is possible to draw an object on a reduced draw window without first having to maximise the view of the draw window. This also allows objects to be more easily drawn when the drawing is being zoomed into.While editing an object, the object can be easily moved to another draw window (simply by dragging the object to the new window, remember to confirm when you get there or it will snap back when you release the left mouse button). Or it can be dragged to a new position not visible in the current draw window (because the draw window is reduced or the drawing is zoomed in) by using the middle mouse button. This is done by grabbing the object, then while the left mouse button is held down, press and hold the middle mouse button, then drag the mouse past the edge of the draw window. The draw window will scroll in the opposite direction.
