simply typing "limewire &" from the shell - works when i first use su, but not from the "normal" user prompt. BTW, I can't see limewire as a process when using top, can only end it with xkill (or the normal clicking the x in the upper-right corner). My comp can be a bit slow, so the task bar icon can take a long time to show any response, but that's not the major problem.
