First it started when I was scrolling in with NUM0 - CAMERA selected with lock camera to view. Everything was ok and out of nothing my camera started flipping and going round in circles and BAM my objects were gone in abyss. After clicking a lot and opening my file with load UI unselected, my objects where on the right place but whenever I selected NUM0 and went into camera mode, everything was gone again. So I deleted the camera and made a new one, and the view is ok now, but whenever I zoom in, after a certain zoom distance my zooming gets slower and slower until it stops zooming. Well at this moment I am still really far from my object. How can I fix this zooming problem?
