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."
The problem no longer happens in latest releases, like 26 and 27.
Not longer an issue in the latest releases.
Finally, somebody reported this except me!
This is a known bug now, and I can tell you exactly hot to reproduce it.
