I have read the memories but I haven't found any questin like that before (though it can be that's only me being dumb).

So, I have *no* idea what I've done to my photoshop, but if I want to bring a picture from it's place to another, it doesn't let me move the picture, but the topmost layer. It doesn't matter if this is an exclusion layer, or anything else, it brings it. Ew? EW!
Someone help me please, I can't use Photoshop like that. *weeps*
