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.
It also just happened to me that unselecting and selecting back the "auto-select" feature has returned to the expected behavior. I am deeply saddened and frustrated every time I encounter a stupidity like this. I wonder what tools are Adobe people using to draw their own interfaces?
