{ Heres a drawbox routine frum my popwindow units...  Its not very optimized,
but its does the job :). may have to change some references to procedures
(eg. txt_color) but thats pretty simple.

             x1 and y1 ... top left col/row
             x2 and y2 ... bottom right col/row
             Ft and Bk ... Sets the foreground/background
             Style ....... box style.
             MSG_S ....... Window ttitle }
