The way this code works is blt::container looks for existing X Windows which 
have the WM_CLASS set to name.  If 3 xclocks are running your script will get 
confused.  This is the problem with KDE apps, they have multiple windows for 
their application and btl::container does not know how to deal with it.

This style of containment does not work so well with 3rd party programs.
