Warning Message "Partially selected objects..." Repeated
The warning message repeats:
"Partially selected objects cannot be set as key objects. In order to set an object as a key object, make sure the entire object is selected and try again."
Finally, somebody reported this except me!
This is a known bug now, and I can tell you exactly hot to reproduce it.
