I am running Motif 1.0 on a Sun3, with SunOS 3.5.  I have been having two
strange problems which I'm hoping someone else has run across.

1) I can't get XtDisplay to work.  My program just hangs at (or just after)
this call.  Instead, I've abandoned XtInitialize, and I'm using its 
component parts, XtToolkitInitialize, XtOpenDisplay (from which I get the
display returned) and XtAppCreateShell.  

2) I can't get a list of the children of a composite widget (a
bulletin_board, for instance).  I use the following code (cw is my
composite widget):


num_children = cw->composite.num_children ;
for (i = 0; i< num_children; i++)
{
    fprintf(stderr, "child %d = %d\n", i, cw->composite.children[i]) ;
    /* My own code goes here */
}

This always bombs out, and if I print the address of the list of children,
it is 0, that is, the way that it is initialized.  I'm confused.  Can
someone out there enlighten me?

Thanks.  rick
