> FWIW, Another path that reliably generates constantly spinning ducks.
1. Open Code Inspections window
2. Open Test Explorer
3. Run a single test or a group of tests.
4. Code Inspections window presents constantly spinning ducks after the test(s).
Work around:
1. Close Code Inspections window (Test Explorer can remain open or be closed)
2. Manually initiate a Parse using the 'Ready' button.
3. After the manually initiated Parse is finished. Open Code Inspections...all is well.
