There seems to be a bug in proctable.  I am trying to add a DeleteWindow
option to my application's menu list.  I want to call the proctableentry
for "frame-delete-window".  The following (simplified)code is from my
InitializeClass:

First I tried:
    struct menulist *myview_menulist = menulist_New();
    struct keymap *myview_keymap = keymap_New();
    struct proctable_Entry *proc;

    proc = proctable_Lookup( "frame-delete-window" ); /* find
    proctable entry */
    if ( proc != NULL )
    {
        keymap_BindToKey( myview_keymap, ATK_CTRL_X ATK_CTRL_D, proc, 0 );
        menulist_AddToML( myview_menulist, ",Delete Window~12",
    proc, 0, MASK1 );
    }

The menu option came up, but selecting it did nothing.  Then I tried
making myown proctable entry which would be passed the frame.  Note
theclass_Load("frame").

    proc = proctable_DefineProc("myview-delete-window",
        deleteWindow, class_Load("frame"), NULL,"delete the current
        window");
    if ( proc != NULL )
    {
        keymap_BindToKey( myview_keymap, ATK_CTRL_X ATK_CTRL_D, proc, 0 );
        menulist_AddToML( myview_menulist, ",Delete Window~12",
    proc, 0, MASK1 );
    }

Again, the menu option came up, but selecting it did nothing.  In fact,
theroutine deleteWindow was not even called!   The prototype looked like:

    static void deleteWindow( struct frame *fr,long ignore );

I also tried inserting a call to proctable_ForceLoaded(proc) in both
ofthe above examples.  No change...

So, I tried passing my own classinfo to the function.  Note
the&myview_classinfo.

    proc = proctable_DefineProc("myview-delete-window",
        deleteWindow, &myview_classinfo, NULL, "deletethe current
        window");
    if ( proc != NULL )
    {
        keymap_BindToKey( myview_keymap, ATK_CTRL_X ATK_CTRL_D, proc, 0 );
        menulist_AddToML( myview_menulist, ",Delete Window~12",
    proc, 0, MASK1 );
    }

with the function prototype as:

    static void deleteWindow( struct myview *self, longignore );

This worked.  My function was called when selected from the menu.  The
problemis, there still is no way for me to call "frame-delete-window". 
Itried "faking" a delete window by destroying the IM, but that just
caused coredumps.

Is this a bug in proctable or is there something else I should be doing.
Note: I don't want to add this to my whole applicationvia an initfile
addmenu.

Any advice would be greatly appreciated.

Thanks,
