I have an example of a method of CListCtrl not getting italicized:
m_listctrlFacility.DeleteAllItems();
I've emailed a screenshot with the subject "VAX 1209 TopicId 1061". Note that it fails to italicize even when not encapsulated in my error-checking macros. Also, the tooltip correctly identifies it as a member of CListCtrl. (I had rebuilt the symbol database before the screenshot was taken.)
In fact, if I open up the C:\\Program Files\\Microsoft Visual Studio\\VC98\\MFC\\Include\\AFXCMN.H file, some of the methods of CListCtrl are italicized, and some are not. I would expect them all to be.
