How to properly use drag and drop with MacBook Pro on OS X 10.7? It seems extremely hard to be able to drag and drop files between two finder windows with a single move on the trackpad - as soon you reach the end of the trackpad you'll drop the files,… in the wrong place.

How can you solve the drag'n'drop problem without using a mouse and still be able to use gestures?
You can use your thumb to click on the lower part of the track and the index finger to move. As long as you keep the trackpad pressed with the thumb you can release the index finger.
