In OS X 10.6 dragging a file(or folder) over another folder in Finder at first highlights that folder and allows you to drop it into the folder as one would imagine. The problem arises after about a second when it then removes the option to drag it over the folder and opens a new finder window with the contents of that folder for you to drag the file into.
I personally find this feature very annoying and it often leads to me moving/copying files into a location I did not intend. I searched through
com.apple.Finder for 'drag', 'drop', 'move', etc. with no luck.
Does anyone know if there is a way to turn this off?
