Thanks for your help. I followed and succeed. However, when I tried to do 
something similar for mouse-left-down, a peculiar behavior occured. The 
standard right-mouse pop-up menu and my custom message box appear 
simutaneously (seemingly). Is there any way to get rid of the standard 
right-mouse pop-up menu?

Thank you very much.
