Something recently is happening to me regarding Groups/Containers: When I open an app, all "children" of a container have the incorrect bounding box size and location. The control is the correct size and in the correct location, even the properties of it are correct. But if I select the bounding box itself and start to move/resize it, the control will jump to that location. This has happened to 3 apps now that I have opened, even a new one I just created. If I rename the control, the bounding box will jump back to the correct size and location around the actual control.
Bad Bounding Box
Resize Bounding Box - Control jumped to location and resized.
