Mine has never dropped when opening.
What mine does, however, is the driver door sags a little. When opening the driver door the top right corner of the window drops and rubs against the seal. The door sags away from the hinge causing the whole door to tilt. Instead of the door being parallel to the body it droops away from it a couple of degrees.
This causes the window to rub on the seal and catch. It needs extra force to open compared to the other doors.
Look at your window as you open the door and see if it does the same thing.
