I'm trying to download a filed from YouSendIt but when I click the Download link I get this message: /Previous Systems.localized/2008-08-22_1059/System/Library/Automator/Get Specified Address Book Items.action/Contents/Resources/English.lproj/AddressBookPanel.nib/nWRdF85g.mp3.part could not be saved, because you cannot change the contents of that folder. This happens only in Firefox, not in Safari. I've gone into the Previous Systems folder and can follow the file thread until I get to here: nWRdF85g.mp3.part Any ideas on how to make this work? (And please don't suggest that I go back to Safari. I prefer Firefox.) Thanks!
