                     46: loncapaclient should work:
                     47: 
                     48: * need to track if they have ever been opened
                     49: * if not,
                     50:    * open when needed
                     51:    * never refer to any object properties
1.3       harris41   52:      * which also means never close
1.2       harris41   53: * if currently open,
                     54:    * just focus when needed
                     55:    * close when needed
                     56:    * can refer to object properties
                     57: * if have been closed,

1.3       harris41   60: The way loncapaclient window "should" work.
1.2       harris41   61: * lonxml makes exceptions for some URI=resources like
                     62:  * /res/adm/pages/menu.html
                     63:  * bookmark stuff.html
                     64: * lonxml should by default
                     65:  * a script command should follow the body tag
                     66:    and 
1.3       harris41   67:    * name the window (loncapaclientURICHECKSUM)
1.2       harris41   68:    * tell remote control it exists
1.3       harris41   69:    * remote control checks clientwindow (opener)
                     70:      and if opener.name is loncapaclientURICHECKSUM
1.2       harris41   71:      it changes this to loncapaclient
