I did some digging and discovered that if I added debug output in the form of an
'alert' dialog box and then waited until the Java applet loaded before clicking
"OK" the applet would load correctly overtime.  So based on that I modified
las.js to repeatedly try to get the map object and to wait before trying again
if it fails.  Specifically, I changed:

  if (map == null){

to loop and wait in between trys (is the a pause or wait in JavaScript?):

  if (map == null){

    for (var i=0; i < 10; ++i){
       var map = top.frames.upper.document.map;
       if (map != null) {
        else {
           for ( var wait=0; wait<10; wait++ ) {
             var words;
             words[0] = "I am";
             words[1] = "On my way";
             words[2] = "Back";
             words[3] = "to";
             words[4] = "the";
             words[5] = "Old";
             words[6] = "Home";
             words[7] = "The";
             words[8] = "Road";
             words[9] = "Winds";
             words[10] = "On";
             var sorted;
             sorted = words.sort();

    if (map == null){


You can test the server by connecting to:


login:		las
password:	lasrules?

If you have problems, please let me know.  More importantly, if you don't have
problems let me know what you think of the interface.
