latest limewire update unexpectedly quitting!

[birdvancan]

hi, i just bought a 1.3 ghz powerbook 12"
latest version of panther and latest......

now limewire is unexpectedly quitting quite often.
the oldedr version worked fine.

i updated my airport card sowftware and security software, etc. and it seems to help the program
run longer...
but, when it happens I am not running any other programs.

I have energy saver set to longest life and sleep for never.
but I have noticed that when screensaver comes on, sometimes it affects limewire.

anyone have suggestions for what could be wrong???

thanks,
J
