If you choose this option, you will be able to view simulations in your browser on the side of the tutorial. However, choosing NO is recommended since the simulations run more smoothly in an Applet Viewer. If you are using MacOS and Netscape, choose NO (your browser doesn't support interactive applets).

If you choose this option, you will need to download an Applet Viewer if you want to view the simulations. This is actually to your advantage because the simulations will run more smoothly and can be viewed offline. You may also view the tutorial without dowloading the viewer, if you don't want to see the simulations.
