I am encountering a problem between Open Look's initialization routine
OlInitialize().  When I use OlInitialize(), the resource database does not work
correctly.  The following program puts up a shell on the screen.  This is
just about the smallest Widget program one can make.

---------------------- A simple program to put up a window --------------------

#include <X11/Intrinsic.h>
#include <X11/StringDefs.h>
#include <X11/Xatom.h>
#include <X11/Shell.h>
#include <Xol/OpenLook.h>

void main(int argc, char *argv[])
   {
   Widget toplevel;	/* Top level Shell */

   /* Initialize the toolkit, and establish display connection */
   toplevel = OlInitialize(argv[0], "Shell", NULL, 0, &argc, argv);

   /* Display and manage the toplevel widget */
   XtRealizeWidget(toplevel);

   /* Enter event loop */
   XtMainLoop();
   }	

--------------------------------------------------------------------------------

I then set up a resource file with the pathname: /lib/X11/app-defaults/Shell

Shell.height: 200
Shell.Weight: 300

When I compile and run the program, the program would return an error telling
me that I did not specify the window height and width.  If I replace the
OlInitialize() with XtInitialize(), it works fine (but then you can't use the
rest of the Open Look toolkit).  It will also work if one change the "Shell" in
the resource file to "shell" with a lowercase letter.  Why does Open Look
refuse to recognize a class resource pattern?  Why is there a difference
OlInitialize() and XtInitialize().  Could anyone who have worked with Open
Look please help shred some light into this strange matter.
