When you say the popmenu is activated do you mean the setpopup routines in the
Data Entry Toolkit?  If I remember correctly those only paint a popup menu on
the canvas.  The Showmenu command displays a ring menu on the top two lines of
the workspace.  To paint the canvas with a copy of what's on the workspace 
before changing the canvas issue a ECHO FAST ECHO OFF command sequence.  This
allows canvas to be displayed with a copy of what's on the workspace such as
tables and menus.  On the BORDB forum of CompuServe you can find a file 
called DanDemo that contains examples of how to program pull down menus.
