I am trying to use the Widget Creation Library to pop up a (say) label
widget when a button is pressed.  This is on a Sun Sparc 1 using WCL 1.03
using the Ari program.  I get a segmentation fault when I press the button.

Here is what I defined in my resource file:

---------
Ari.WcChildren:		command
Ari.title:		Test

*title1.wcClass:		commandWidgetClass
*title1.label:			press for popup 
*title1.callback:		WcPopupGrabCB( *about )

# I thought this would work:
*about.wcClass:			overrideWidgetCLass
*about.wcChildren:		hello

# or this:
*about.wcConstructor:		XtCreatePopupShell
*about.wcChildren:		hello

# This is just the popped up label
*hello.wcClass:			labelWidgetClass
*hello.label:			Hello World
-----------

There is an example in the WCL distribution using the translation table
and actions, but is seems that I should just be able to use the command
button's callback to pop up another widget.  Any help is appreciated.
