Lightroom 4.1: Tone curve: Difficult to move a point vertically along the left or right edges

When in "edit point curve" mode, it is possible to move the points along all four edges of the diagram, which can be useful for special effects - especially when moving the endpoints e.g. to lighten up the photo for use as a nearly-white background, or to blow out highlights.

However, it is a problem to move points along the left and right edges: The moment the mouse cursor is moved a little more than some pixels outside the diagram, LR interprets this as "delete this point" or - if no more points are there to delete - simply lets the point jump back to its original position. Fortunately, the point is not deleted until the mouse button is released - it reappears when moving the mouse back towards the diagram.

The problem is aggravated a little bit because one cannot see the mouse pointer during movement of the tone curve point. So one has to pay attention to move the mouse exactly vertically, or at least move the point a little bit inside the diagram and move it back to the edge when finished, which is very cumbersome.

There are two possible solutions IMHO:

1. Remove the "delete point by dragging out of diagram" feature entirely - one can still delete points by double-clicking or context menu. This feature is not documented anyway (well OK, double-clicking isn't documented either ;-).

2. Make the "delete threshold" distance significantly larger (there is more than enough room left and right of the diagram), and possibly don't hide the mouse pointer when dragging a point (or show it at least when it is outside the diagram).

P.S. Lightroom 4.1 64 Bit on Windows 7 64 Bit.

By the way: When hovering over a point in "edit point curve" mode, a four-arrow mouse cursor would make more sense than the currently used vertical two-arrow cursor.
