picture layout

Hi,
I'm starting to use Morpheus Suite 3.0 Industrial.
In the Picture Layout dialog the "Scale the picture..." options are greyed out.
(The pictures are JPGs)
Also - what's more important for me - I try to scale the picture using the mouse while keeping the ratio.
In some drawing software (like OpenOffice Draw) that can be done with holding SHIFT while using the mouse.
Do you have something similar in your product?
Many thanks in advance
