Since I upgraded to CS6 I've lost my favorite feature in CS5 - selecting a layer by clicking on the item in the image. I now have to find it in the layer's list & highlight it. I've checked preferences & everything I can think of but can't find a way to make it work. HELP!!!
If this is happening in a specific file only, not in other PSDs, then you've probably created a mask in the Channels tab, one that covers the whole image. Delete that mask form the Channels tab and it should work fine.
