=====
To avoid the problem with multiple inclusion of the same header file (if
that is the problem you are having) you have to change the header file
in question to include the following code:


-------------------------   panel.h:  ---------------------------------
#ifndef __PANEL_H
#define __PANEL_H

/*
 *  Content of header file. Once defined __PANEL_H we avoid the double 
 *  inclusion of the header file.
 */

#endif
-----------------------------------------------------------------------
