Camera movement and pan became exponentialy small in a large scene

I have go a large scene . When I pan and move camera with CTRL and SHIFT the speed is getting slower and slower until I can not move at all. I can rotate normally though. How do I override this behaviour? Scaling the scene seems not to help. Thank You very much. :slight_smile:

Try View Selected in the Select menu on the 3D view, or . on the keypad. This often cleans up this sort of thing.
