After upgrading in product Next & Previous image navigation doesn't work! How to fix?

Hello.

After upgrading to NC 3.90 Next & Previous (left/right buttons) image navigation does not work.
When you zoom an image you cannot click right or left in order to see next or previos image. It doesn't work.
Before in 3.50 it was working fine...

How to fix< or maybe is there some special setting for it?

Thanks.
