I have a parent and child boxes. Both have position set to freeform. When I select them both (shift+click) and move them around the artboard they get misaligned. I.e. the child element moves relative to the parent with the same distance and direction the parent moves relative to the artboard.
Here's a screen capture: https://www.dropbox.com/s/fcw4vk9hy2mh8d3/subform-bug-screencast-12-11.mp4?dl=0
