Original report text

Center of rotation is not updated in perspective view mode, during transfer with 3D-mouse.
In perspective view mode the normal mouse operations sets rotating center in correct postion.
Using 3D-mouse the rotation center is not updated. This makes it very difficult to use 3D-mouse in prespective view mode.
Tested with 3DConnexion's SpacePilot Pro.

Steps to reproduce

1. Open FreeCAD.
2. Create new part (cube).
3. Change view mode to perspective view.
4. Rotate cube with 3D-mouse. Rotation center is in cube's center.
5. Move cube away from it's original position by using 3D-mouse. Zoom the view with 3D-mouse, not that cube it self has to move
6. Rotate cube again with 3D-mouse. Rotation center has not transferred with the cube.
   Instead rotation center is still at the old location.
7. Rotate cube with normal mouse. Cube jumps to to it's original location (rotation center) before it starts rotate.

Correction to reproduction:
In reproduce step 6, I ment to say that: zoom the view with 3D-mouse, not that cube it self has to move.

is this still relevant? anybody else with a 3d mouse can check this?

@chennes, you do right ?

Yeah - I don't think I am reproducing this exact behavior, but I definitely get some rotation glitches in perspective view, with sudden jumps between angles. Maybe I'm just garbage at using the mouse (I am still new at it), but it doesn't seem right to me.
