I updated my Gamestudio for 6.50 version and I can't move the camera in Preview Level. I tried to use the arrows and mouse, but nothing work. What's going on? Do I have to set a movement script to navigate through my level?
That happens both in WED and MED.

Maybe you should press "0" at first.

Perhaps pressing zero key could help.

Ah, yes! It works. Thank you for your attention.
