Hi again Alexandre
sorry to hear you are still having problems--the safe boot and upload throttle should have done the trick.
Incomplete files can't be resumed without the index--stored in the downloads.dat file and backed up with the downloads.bak file. So if you move the incomplete folder, dragging out individual files won't work. You're right that the best way to handle bad incompletes is just to delete them from within the Library. Generally it's best not to try messing with incompletes (voice of past failures
).
I still think there's something wrong at the system level though.
For awaiting sources, just control-click the search tab and choose "repeat search"
