Yeah I have this problem! When I first got the car I noticed that the drivers door jumped when opened, so I adjusted the striker plate to sort that out. But it still sticks! I think it's because of the rubber surround on the door frame, it just gets settled into the 'A' pillar of the car. And with all 3-door cars, as the 'Teg has long doors, they always take more effort to open! - sorry, no solution!
