Whenever I try to delete a file in Finder I get "Finder wants to make changes. Type your password to allow this." I can't figure out why Finder isn't letting me delete files under my home directory without providing my password. Here's a listing of some files on my desktop:

~/Desktop steve 526$ ls -l@ flower*

When I try to delete a file from Finder, I get this:



Here's a listing of my home directory. The permissions all look reasonable to me.

I can delete the files from Terminal with rm flower1.png without problem. Why is Finder being so picky?

I already tried repairing permissions in Disk Utility.

Edit
Sorry, forgot to mention that I'm running OS X Lion 10.7.4.
OS X asks for a password whenever you try to delete a file because your ~/.Trash folder belongs to the root user and has permissions drwx------ — noone but root can read, write or open this folder. Being in the same situation I tried the command shown below in Terminal and it helped:

sudo chown -R steve:staff ~/.Trash


Note that I've changed my username to yours in this example. Also note that sudo command will ask you for user password — it's OK.
