I'm using Blender 2.76 under Windows. Every time when I try to position the 3D Cursor, one coordinate is set too far away from the screen - e.g.:
- I load the startup file.
- I press Numpad 5, Numpad 1 to enter "front ortho" view.
- I left-click beneath the cube.
I get a 'Y' coordinate of -260.91177!! - which is very far in the front of the scene.
So, it is impossible to place a new object ...
