music skips during playback while searching

anyone else experiance a problem with music skipping and stuttering while a search is in progress. if i am playing a song in winamp and do a search in limewire for music the song playing will skip like crazy until the search has finished. only does it when the searchs are calculating fast. i have a p4 1.5 gighz 256 megs of ram and useing limewire 2.0 and it also did it on previous versions. also running on a cable modem.
