On the curves adjustment I am not able to perform fine movements of the points I am adding.
If you add a point and try to move it then it will stay in the same position until the mouse pointer is a few pixels away from the original position that I placed the point.
After this you will not be able to move the point to within a few pixels of the placement position. It will snap and skip over it.
It prevents fine control of the curves, or at least makes it more difficult.
Am I missing a setting or something?
