- in CNCJob UI Autolevelling: solved some small errors: when manual adding probe points dragging the mouse with left button pressed created selection rectangles; detection of click inside the solid geometry was failing

- in CNCJob UI Autolevelling: in manual adding of probe points make sure you always add a first probe point in origin
