Comment 2 Mike Kaganski 2020-08-11 10:28:35 UTC
A code pointer:

WriterInspectorTextPanel's AttrChangedNotify tries to get a "current" shell, which might change over time, while the panel should be bound to the original shell.

On the other hand, Writer's SI captures a SwWrtShell in its ctor, which is what may be used later everywhere when it needs any shell. E.g., the SwWrtShell is the shell that provides cursor itself; to get document shell from SwWrtShell, you call m_pShell->GetDoc()->GetDocShell().
