Hi, I use Azureus for my bit torrent client. And ever since I reformatted from XP-home to XP-pro I've had a simple but undisclosed problem with it. Basically when I open Azureus to DL something it dl's and I get good up and down speeds while I'm on the machine keeping windows active. But if I leave the computer and let it go idle every time I come back the connection has dropped and I have to restart the computer and modem to re-establish the connection. I'm not using a router by the way. Thanks.

Perhaps you need to disable screensaver/sleep mode on your machine? That's usually the cause of such things.
