If I try to delete any file from any folder inside Macintosh HD, it prompts me for my password. I've repaired my disk in Disk Utility, no problems. I disabled the password to see if that would help as a temporary solution, but it still prompts for the password (I just have to hit enter to delete the file now, still, annoying). Also, when attempting to view the trash it displays no information and I can not empty it, nor force empty. When running Lion Cache Cleaner it says I have 5 items in my trash, totaling 0 KB. I'm running Mac OS X 10.7.1 on a 2011 iMac. This has been occurring since updating to Lion, from Snow Leopard, I believe.
