--- Comment #14 from Rosanne DiMesio dimesio@earthlink.net 2012-02-03 17:32:40 CST --- In 1.4-rc2:
Office 2007 & 2010--online help works, and displays the results in the system's default browser; searching offline help produces an unformatted list of topics that should be links to articles, but which aren't.
Office 2003--online help now opens Wine's IE with a blank window, but other than that the situation is the same as in comment 12.
