If you are using Google Chrome:
Google Chrome no longer supports Java and CDFs. Therefore, to view Atractor's applets or CDFs, use a browser other than Chrome.
If you are using another browser and still have problems with the applets
Currently, many browsers are blocking Java, preventing the user of seeing applets. What to do?
- The first step is to install the latest version of Java and update your browser version.
- Then, on your computer, if you are using Windows, select the Control Panel; if you have a Mac, choose System Preferences.
