Sherry,
If you're generating WinHelp 2000, TOC auto-synchronization
is enabled by default, but it only works to the extent that the
topic is listed in the TOC. If you click on a link within your
WinHelp 2000 file to a topic that does not have an entry in the
TOC, "nothing" appears to happen, but as soon as you click a link
to a topic that has a TOC entry, the TOC will auto-synchronize to
the specific topic as soon as it appears in the topic pane. Of
course, if you're generating some other kind of output within the
RH for Word IDE, you'll need to check the appropriate setting in
the Properties dialog for the layout you've selected (WebHelp:
third screen; HTML Help: final screen, Advanced button - Tri-Pane
tab; FlashHelp: third screen).
HTH,
