I have created a child window with the following
code
hp->hpw.top = XtVaCreatePopupShell ("radio_hardware_parameters_setup",
topLevelShellWidgetClass,
parent,
wargs,
n);

parent is the parent shell. When I close
the parent I get an error message
Error XtPopdown requires a subclass
of shellWidgetClass.
This error seems to be random, so what
do I need to do create this child window
correctly?
