Since I installed 10.4.1, I haven't been able to rename any file or folder. These aren't locked files or anything, and I do have permission to read and write, but I can't seem to rename anything. Even when I create a new folder, I cannot name it. It stays as "Untitled Folder." If I single click on the name of a named file, it usually lets me edit it. It does let me get to the name, but when I hit delete, or fn + delete, nothing happens. And if I right-click on the mouse and try to find the "rename" option, its not there. What the heck? I may want to name or rename some files in the future. Any suggestions? Is there a .plist file or system file that I can delete and have it repair itself? Will I need to do an Archive and Install to fix this? It's rather important.
