---------------
I have had some problems posting to news recently, so this may be a
repeat.  If so, I apologize.
---------------
I am running X11R4 on a Sun 3/60, SunOS 4.0.3 and trying to upgrade
an application that uses the Athena widget set.  A Dialog widget that
displays a default string value works under R3 but not under R4.  An X
protocol error occurs using the following code.  The "root_wid" is of the
"formWidgetClass".

I would appreciate any insight into what I might be doing wrong.
The release notes indicate that changes are not necessary for the Dialog
widget, but then again ... 

static  Arg     dialogArgs [] = {       /* dialog widget set-up */
        { XtNhorizDistance,     (XtArgVal) 20 },  /* Form widget resource */
        { XtNvertDistance,      (XtArgVal) 60 },  /* Form widget resource */
        { XtNwidth,  (XtArgVal) 200 },
        { XtNheight,  (XtArgVal) 70 },
        { XtNlabel,  NULL },
        { XtNvalue,  NULL },
    };  /* dialogArgs */

char            *dest_folder;
char            *malloc ();
    dest_folder = malloc ( 100 );


/* subset of callback code follows */

char    *dialog_label = "Enter destination folder name:";

        if ( ! *dest_folder )
            strcpy ( dest_folder, "default_folder" );
	XawPanedSetRefigureMode ( pane, False );

        dialogArgs[2].value = (XtArgVal) 220;
        dialogArgs[4].value = (XtArgVal) dialog_label;
        dialogArgs[5].value = (XtArgVal) dest_folder;

        dialog = XtCreateManagedWidget ( "dialog", dialogWidgetClass,
			root_wid, dialogArgs, XtNumber (dialogArgs) );

        XawDialogAddButton ( dialog, "OK", Ok, client_data );
        XawDialogAddButton ( dialog, "CANCEL", Cancel, (caddr_t) NULL );

        XtRealizeWidget ( dialog );

This all works when the "XtNvalue" resource is set to NULL, but not
when an initial value is assigned (as above).

The X Protocol message:

X Error of failed request:  BadWindow (invalid Window parameter)
  Major opcode of failed request:  38 (X_QueryPointer)
  Minor opcode of failed request:  0
  Resource id in failed request:  0x0
  Serial number of failed request:  205
  Current serial number in output stream:  205
