I trying to get XmForm to accept a particular layout that I want between
a ScrolledWindow and a PushButton but when I define the layout XmForm complains
and produces a scrambled layout. Here's the layout that I want:

+-------------------XmForm--------------------------+
|                                                   |
|+---------------------+                            |
||                     |                            |
||                     |                            |
|| ScrolledWindow      |       other widgets        |
||                     |                            |
||                     |                            |
|+---------------------+                            |
|                +-----+                            |
|                |PushB|                            |
|                +-----+                            |
+---------------------------------------------------+

The constraint that I want is that the bottom of the ScrolledWindow is to
tied to the top of the PushButton and that the right side of the PushButton
is to be tied to the right side of the ScrolledWindow.

When I use the following code:

   n = 0;
   XtSetArg(args[n], XmNleftAttachment,  (XtArgVal) XmATTACH_FORM); n++;
   XtSetArg(args[n], XmNrightAttachment, (XtArgVal) XmATTACH_POSITION); n++;
   XtSetArg(args[n], XmNrightPosition,   (XtArgVal) 50); n++;
   viewport[file1] = XmCreateScrolledWindow(outer_widget, "view1", args, n);
   . . . 
   n = 0;
   XtSetArg(args[n], XmNtopAttachment,    (XtArgVal) XmATTACH_NONE); n++;
   XtSetArg(args[n], XmNleftAttachment,   (XtArgVal) XmATTACH_NONE); n++;
   XtSetArg(args[n], XmNbottomAttachment, (XtArgVal) XmATTACH_FORM); n++;
   scan_widget[file1] = XmCreatePushButton(outer_widget, "scan1", args, n);
   XtVaSetValues(viewport[file1],
		 XmNbottomAttachment, (XtArgVal) XmATTACH_WIDGET,
		 XmNbottomWidget,     (XtArgVal) scan_widget[file1],
		 NULL);
   XtManageChild(viewport[file1]);

   XtVaSetValues(scan_widget[file1],
		 XmNrightAttachment, (XtArgVal) XmATTACH_OPPOSITE_WIDGET,
		 XmNrightWidget,     (XtArgVal) viewport[file1],
		 NULL);
   XtManageChild(scan_widget[file1]);

I get:
Warning:
    Name: form
    Class: XmForm
    Circular dependency in Form children.

Where is the circular dependency? And can I do what I want with XmForm?? Thanks
