Thx Lindal, but no. "Disable camera constraints" was not checked. I set mouse controls on very slow and used another mouse, but .. no improvement at all. It is strange, pointing at an object and moving the mouse the slightest tick (a milimeter movement) makes the view jump very very close or right in the object. Ok well, i m not using sl and waiting for an update that fixes it since four months now and can wait some more months. thx
