Hmm, you might wanna reduce the number of days you wanna keep the incompletes as I read somewhere in these forums that cleaning your incompletes actually might contribute to a better working Limewire for you.
I also think now that this setting applies to the library incompletes rather than the search window but again, I'm NOT sure.
