Drag and drop

I upgraded to lion a while ago and found something that bugged me but never did anything about it. In Snow Leopard when I dragged a file into a folder, it would open the folder. This was useful when I was dragging something into say documents>dropbox>documents but now I have the drop the file for each step of the way rather than holding it all the way through. Is this a new thing or is there a setting I can switch?

 

Is there a way to do it automatically?

 

Should have thought of that, now I feel .
