I think you need to call setHelp() passing the Control that is returned
from createDialogArea() instead of the parent argument. Like this:
Hope this helps,

It seems to depend on what control has focus when the Help button is
clicked. In our dialogs I call setHelp() for the result of
DialogPage.getControl() AND the Control that is returned from
createDialogControl(), and that seems to work regardless of where the
user clicks (or doesn't click) before clicking the ? button.
Hope this helps,
Eric
