Problems with Helpviewer and sections(Tabs)

The helpviewer included with QNX 6.2.1 PE really got problems using
An example: First I open a new section(CTRL+N). I then click “Dinkun
Documentation” in the topic menu.
I then follow some links to other pages. Then I use my mouse to switch
to the new section, and then back to
the section with the Dinkun documentation, and then this content of this
section is back to the mainpage of
the dinkun documentation.
I sometimes have the same problem with only 1 section where it sometimes
reset the content to the
Documentaiton Roadmap page if I switch between the helpviewer and other

Is this a known problem or did I do something my helpviewer did not like?
