Camera view

Hi folks!

I have a problem with the “camera view”, num0
When I switch to that view, then I see the scene about from the direction of the camera. But really just “ABOUT” from the cam’s view. Actually, the view is too high. I see the outer picture limit at the bottom of the window. Enlarging the window doesn’t help. Changing the view donwards puts the view to the right angle, but it’s not “camera view” anymore, but “custom view”, of course.
Setting the camera to the actual view works fine, but as soon as this is performed, my actual view goes up again, showing the upper frame of the camera, as before.

What could be the problem??

Regards
Simon
