1. Create a picture frame using the Picture Frame Rectangle Tool.
2. Drag an image from Finder into that picture frame.
3. Select Move Tool.
4. Click on picture so that it is selected. Click the picture, hold and drag. Instead of the picture frame moving, the move tool draws a selection box which disappears upon release. (You can see me fighting with this here: https://youtu.be/dlnF_8fO3hA. I try the node tool and the picture frame tool also.)
Double clicking on the picture frame allows you to move the image *within* the frame, but not the frame itself. To my knowledge, the nodes are not functional as you don't seem to be able to resize the picture frame either.
