@ Rick, On one hand you are right. A simple low graphical cost system like truevision has benefits. It takes lesser space, quicker navigation, better overview.
However in the world of today where visuals are becoming more important. personally I am okay with this but there will be many people who will complain that this style is to 'old looking'. Ofcourse many programs still use this kind of help system.
If this documentation style can be mixed with easily swapping of several languages and a little more(slightly improved)graphics. Plus, I think this style is easier for offline documentation.
