I know it's a bit of a thread resurrection but since I upgraded to mountain lion I've noticed that the news that's scheduled to download at 6:30am doesn't until I wake the MAC. Before it used to download the papers.
The computer is set to sleep after 3 hours & under Lion it did used to wake.
The other that may or may not be related is one of the papers (Guardian & Observer UK) hardly ever downloads correctly now. It only downloads a few hundred KB whereas if I manually download it's fine.
