I am using a big mac, so I have a lot of storage and memory. I downloaded a world that was made a long time ago, it had to be unzipped or something from inside the mine craft client. Now, when I play it, my mine craft freezes momentarily. What should i do? Also, some of the painting started popping off after I went from the recent snapshot to 1.7.2.
