Game from scratch C++ and SFML Edition

[twiggystardust]

Has anyone ever used this tutorial? I did a while back and it worked all fine and everything, I was using SFML 1.6 that time and I decided to try it again after abandoning SFML for awhile, so now I've decided to do the same tutorial, but use SFML 2.1, and this time I got to chapter 6 (when you start adding movement) and the movement is super choppy, and on the menu, clicking the play button is touchy, I don't know if this is because I used 2.1, but if anything, I would think it would run more smoothly, anyone have any ideas?
