When I place a picture frame and "place" an image into the frame, the image is scaled in proportion when I drag the anchors around.
When I place a picture and "move" the layer "into" a picture frame, the image is not scaled inproportion when I drag the anchors around. The "properties" menu in the picture frame does not help with constraining the image to scaled/unscaled proportions. (BTW: The "done" and "cancel" buttons are way off in that menu)
Is that an error? I think this is not logical, as I often place an image and realize later that I want a certain shape or frame to limit the extents of the image.
