I am running Scratch on a Windows 7 Lenova computer, preparing for teaching middle school students to program. It appears that the scripts in Pong are having problems. The coordinates don't seem to work like they should. (i.e. ball passes through the paddle at times, and the bounce (direction) doesn't seem to work well. Is there something I can do to adjust my computer to make the programs work as planned. (Wondering about resolution, speed? etc)
