The collective wisdom of the net will have to supply the leadership
to guide new X programmers.   There is an enormous demand for my
time, and Chris is very probably in a similar position.  Now there 
are many programmers who could step in and answer questions; I 
encourage them to post answers.

Good, right on the mark.

When you create the Athena Toggle widget, you supply some radio data:

> 	XtSetArg(arg[n], XtNradioData, "phone"); ++n;
> 
> 	Type_Phone = XtCreateManagedWidget("phone", toggleWidgetClass, 

When you call this function, you are specifying different radio data:

> 	 XawToggleSetCurrent(Type_Mail, "phone");

The value of the radio data resource is a pointer.  These two "phone"
strings have different addresses.  If the radio data doesn't match,
this function has no effect.
