Thanks for your reply. I have a 650MHZ processor, 256 SDRAM, 60GB HDD (40GB free), Windows XP home edition, Java 2 runtime environment standard edition V1.3.1_O4, Limewire 4.0.8, 512 ADSL connection. I measure my cpu usage from the task manager thumbnail 'performance'. I will go now and search for an update for java.

Thanks again for taking the time to reply
