Finder stopped showing file info
Running OSX 10.6.8 on iMac. Recently noticed that Finder has stopped showing file info and thumbnails when I click on files in list view with columns. Repairing privileges and restarting has not resolved the problem. I'm able to see file info when I hit command-I, but otherwise, simply clicking on the file name no longer shows the mini preview that's so convenient. How to restore this function in Finder?
