The X windows systems takes a layered approach:
Unix ----> X Windows Library ----> Other X Higher level libaries ----> Motif
Each layer builds on the capabilities of the lower levels. Motif describes
a particular "look and feel" for X windows. Programs call particular Motif
functions which then call down through the chain, eventually calling into the
X functions and then Unix kernel functions.
The particular functionality of the DUI program comes from using the look and
feel of Motif. Motif does have a large set of parameters which defines its
own look and feel. I belive that the part you are talking about has to do with
the behavior of a window's own task bar. We had decided to make the center
portion of each bar a context sensitive help area. That is why you can't
grab it as you describe. I will check with the software guys to see if there
isn't something that can be done to compromise on this situation.
