     Sounds like your "window_file" does not use the proper shell
     widget name, i.e. if appName here is "foo", the file must
     define "foo.wcChildren: ...".

     Also, if you don't want to get confused by the resources from
     the previous/initial "loop", you may consider the following:

     After the app initialization, make a copy of the Xrm databse
     containing all the resources gained through the Xt search pattern.
     In each loop, destroy the current dpy->dp and replace it with
     a copy of the "initial one", then load the new resource file(s).
     This will prevent your Xrm databse from growing (it won't grow
     if you constantly overwrite the same resources, but is this the case?).
     The Wcl code can be used as a guide ...
