Not trying to be difficult here trying to understand - if I open something, drag it and drop it and close it? It seems to be the main file size I think that causes me problems. For example if I have lots of layers and then I want to move something - move a layer or transform it for example - it either doesn't move for a very long time (so I can't control it) or it moves very very very slowly........or the whole thing locks up........or PS crashes - those were the kinds of things I was experiencing.........With just the huge 16 bit many layers file open - nothing else at the same time. And yes I must remember to file place.
