Why does Limewire forget to renew downloads if the downloads are interrupted for whatever reason? After leaving the computer on for several hours, day, days, etc. I select all the files stopped and RESUME them, then they continue. Doesn't Limewire automatically do this, or suppose to do it?

Have I set a preference incorrectly? I've set downloads to CLEAR auto.
