==================================

When you open the Lister window (F3 key) on a C-Munipack photometry file
or C-Munipack catalog file, the window is opened in the "Image or multimedia" 
display mode and a chart is presented in the window. If the file is very big (>16 MB), 
you have to switch the display mode manually ('4' key).
