WinHelp uses page and section breaks for a radically different purpose from print RTF. Page breaks are reinterpreted to mean “start of topic”, and a definite sequence of codes must follow the topic start in the prescribed order. DITA2Go creates this sequence automatically when you specify [HelpStyles]ParaFmt=Topic (see §17.7.2 Assigning properties to formats for topics and hotspots).
Section breaks are used as an undocumented modifier to page breaks; they permit the help compiler to avoid going into convulsions if the first thing after a page break is a table. Unless you are converting to WinHelp on an Altura system, use the default setting for section breaks:
[HelpOptions] ; HelpSectionBreaks = Yes (default) for sect break before each topic, ; or No for Altura (filter strips table format from topic titles) HelpSectionBreaks=Yes
The following options have no use in WinHelp; set them as indicated (the WinHelp defaults):
[HelpOptions] PageBreaks=Remove KeepSectBreaks=No
