This question is not related to a similar question I posted previously 
regarding command line arguments.  That problem is solved - this is 
different.   I made a program that draws Lissajous patterns (periodic 
graphs) using sine functions and exponential functions.  There are many 
parameters that affect the display of these graphs. There is 'front end' 
code that allows user to set these parameters using scanf.  This front 
end should query the user any time the program is started - indeed it 
does when the program is started from the command line.  I have an icon 
on my Ubuntu desktop that starts the program when you double click the 
icon - however when you do it that way none of the user querys are 
executed.  The program simply runs using the values initialized when the 
variables were declared. This behavior is a mystery to me. How does it 
skip over the front end code? I have another simpler program structured 
the same way and it has the same behavior when started by double clicking 
the icon.

TIA.   Bill S.
