Make Downloads Continue When Idle...

Hey, I have a question.

When i'm using limewire to download a bunch of files at one time, if i leave my computer for a long enough time, the downloads stop.

I come back and the download speeds have all been reduced to zero. After i shut limewire off and turn it back on, they start downloading again.

I have disabled automatic sleep in the energy saver, but is there anything else i can do?
I want to be able to keep downloading over night when i'm asleep.

Thanks

If you snore when you're asleep, then place the mouse dangling over your mouth or nose. This will prevent LW from idle mode. Idle mode should not affect downloads. It doesn't for most people. It may in fact be related to your ISP setup. I've heard some require browsing or else they go a little inactive. If this rare scenario should be yours then you could keep an online page (one that refreshes every minute or so) in your browser active.
