Resizing Images - Constrain Dimensions..

When inserting an image into the body of an email, how do you resize the image and constrain the dimensions? It looks like resizing by dragging a corner screws with the dimensions. I tried holding down shift, ctrl, alt etc like in Photoshop or other tools and had no joy - is it possible?

Is there a fix to this? We are having the same issues.


It is not possible at the moment, but I will discuss it with our developers and will let you know.
