I have a file that appears in the trash after every boot that can not be deleted, but when you drag it to the desktop it disappears. It seems to be the only way to remove it. You get no error message anytime. The file just has a bunch of ~~~~~ for identification. What caused this and how do you remove it??? New 2009 3.06 iMac running latest version of Leopard. No issues at all with machine.
