My Finder file detail headers looks weird My Finder's file details header looks weird.



It looks translucent and not clickable :(
I used many command-line tools on this Temp folder, so I could be happen from accidental deletion of some system file. But I can't figure out what actually happen in there.

How can I fix this?
You used View » Arrange By or a ctrl+&#x2318;+[number] shortcut. It's new in Lion. Remove it by selecting View » Arrange By » None (or pressing ctrl+&#x2318;+0).

Hold down &#x2325; while opening the View menu to get the older Sort By… menu, or press ctrl+&#x2325;+&#x2318;+[number] instead.
