BlackBox Component Builder

When clicking on a link to a help text that is already open within BlackBox,
a new help text window is opened. This is in contrast to the expected behavior of
reusing the open window (bring to front) as it is done when editing documents.
The reason is a very unsystematic treatment of reuse of open documents in BB 1.6
based mainly on the window title.
Related anomalies arise with other document modes (except edit mode)
and need to be taken into account when changing this behavior.
There are also cases with tool dialogs where there is a wrong reuse if
the same window title is used for different documents.
A proposal for a systematic treatment of reuse of open documents based on
file name, location and document flags instead of window titles is available in CPC 1.7 rc5.

Refers to CPC 1.7 rc5 change list item 9 and Open Points 05.
