+ - Crash during garbage collection deleting a QDockWidget, often from DockPrep.
+ - Crash in Qt setParentChanged() where it appears ChimeraX is exiting normally in Py_FinalizeEx() and atexit_callfuncs().  But Elaine hit this crash and she was not quitting, was changing Mac scrollbar auto display setting.

+ - Tom trying latest OpenFold preview 2 released a week ago.  Reran antiviral ligand geometry tests.  Small improvement.
