Haven't checked on that yet, as neither me > nor my computer tend to go to sleep while working :) I've never let my ICD2 run for a long time in programmer mode, but I have in debug mode and mine didn't do anything like that either. One other thing the OP can check is the USB root hub's power settings, in win2k there's an extra pane in one of the USB devices that says: allow windows to turn off this device to save power. Make sure that's not selected. If that's not it then it's possible the OP has a bad ICD2. To the original OP, does it ALWAYS happen?
