Thanks for the reply.  However, using the slider created with your 
command cannot move the palette ABOVE the bottom of the main title bar, 
at least not on my system.  After executing the commands written in your 
message, when I drag the created slider upward with my mouse, the 
palette faithfully tracks the slider position until the top edge of the 
palette reaches the bottom edge of the main title bar.  Thereafter, as I 
continue to drag the slider upward, the palette does not respond.

Increasing the vertical coordinates of the initial position and/or that 
of the maximum slider position the numerical parameters in the 
Manipulate command still does not allow the palette to be position above 
the bottom  edge of the main title bar.  So far, the only way I have 
found to get the palette above the bottom edge of the title bar is to 
drag it manually with the mouse.
