Trouble with 'Curve Follow' in 2.37/camera squares.

I tried to make a simple roller coaster animation, and when it came time to have the camera always pointing forward, It would not work for me. I recall getting it to work in 2.36, and I don’t know if I’m doing something different now, or if there is something new in 2.37, or what. Could someone help me out?

EDIT: Thank you for your promp reply, I tried it and it worked. I’m glad that that part hasn’t changed. Now I have another question. When animating the camera, in the demo files, there are little squares that the camera goes through. How could I use that feature. Is it new?? I didn’t think that another thread would be nessary.

remember to set your curve to ‘curve path’ and ‘curve follow’ >before< you parent your object to it, then just use ‘normal parent’
