This morning I turned on my computer and found a strange issue. I can not save files anywhere except /Users/<ME>/Downloads I can tell my browser to save the file to another location, but it fails. I just see the *.part file in /Downloads. But it never gets moved/renamed to the location I specified. It also doesn't show up in my browser's list of downloads. This is not a new Mac. I did not update any software. I am running 10.8 on a 2011 Mac Mini. It happens in Firefox and Safari. Any ideas?
