SUMMARY
Moving imported C++ classes around in class diagram often results in inheritance and has-a connections not moving with the class.

STEPS TO REPRODUCE
1. Import some C++ classes with has-a and inheritance relationships between them
2. Drag these into a class diagram
3. Move a class related to another in the diagram

OBSERVED RESULT
The class will move as expected, but the link with the other class will not. Furthermore, moving the other class results in an orphaned link.

EXPECTED RESULT
The links should move with the class
