Well murasame is kinda wrong
, on os 9 it is options (only os x has preferences). Kevin, do you have apple java mrj 2.2.5? This seems to be a problem of java. Also, try to reboot your computer to see if it fixes the problem. Another tip: don't forget to increase the ram allowed to LW (apple-i, then set the max memory to 80 000k).
Bonne chance
