 This script was tested with the following systems and browsers:

 - Windows XP: IE 6, NN 7, Opera 7 + 9, Firefox 2
 - Mac OS X:   IE 5, Safari 1

 If you use another browser or system, this script may not work for you - sorry.

-----------------------------------------------------------------------------------------------------------

 NOTES:

 - Sound was successfully tested only on Windows with IE 6 and NN 4; Firefox needs a plugin; Opera 7 + 9
   behave very strange when sound is embedded, so for the moment it's disabled for that browser

 - NN 4 on Windows and IE 5 on Mac OS don't view elements (text etc.) below the game area properly; they
   will appear underneath the game area instead

 - IE 5 and Safari 1 on Mac OS show a very poor performance (game is too slow)

 - Movement with arrow keys doesn't work with Opera 7 and NN 4 on Windows and Safari 1 on Mac OS; Safari 1
   and Opera 7 actually don't recognize any key
