Java Chess Viewer Troubleshooting

If the Chess Viewer launches, but looks distorted or incomplete, make sure your browser has "zoom" set to 100% (not higher).

If you get a white screen (or a black screen) when you launch the Chess Viewer, follow the steps on this page.

Firefox 3.6.14 has a bug that interferes with Java. If you have this version, please update Firefox.

1. Get the Right Browser

The "SBC" or "Yahoo" browser does not work with the Java Chess Viewer.

We recommend the Firefox browser (formerly, Netscape) which is a free download from here:

We do not recommend the AOL browser. Please use Firefox, Safari, Chrome or Internet Explorer instead.

If you have trouble with Internet Explorer, please try Firefox.

2. Get the Java Update

There is an easy way to find out if Java is installed correctly.

Go to You'll see a button that says Free Java Download. Just below that, click where it says "Do I have Java" to see if you have the current version of Java installed. If you are not current, use the Download link to update your Java version.

3. Let Your Browser Use Java

You may need to tell your Web Browser that it has permission to use Java.

If you are using Internet Explorer, go to Tools - Internet Options - Security. Click "Custom Level", go down to SCRIPTING and turn on

"Active Scripting" - ENABLE


"Scripting of Java Applets" - ENABLE

... and click "Save Settings".

In Firefox, go to Tools - Options - Content. Make sure "Enable Java" is checked, and click "OK".

5. Check Your Firewall

You may need to configure your Firewall. Here's how.

Try loading the "Learn to Play" applet. Navigate to:

and click where it says "Click Here to Learn to Play Chess".

If the applet loads and you see a popup window, click "Learn the Rules".

If you click Learn the Rules and nothing happens, then the problem is "Active Content". If you just get a blank screen, it is the same problem.

However, if you can use the "Learn to Play" applet, but you still can't enter the Training Room, then the problem is "Cookies".

Zone Alarm, Norton Utilities, and other firewalls can interfere by blocking Active Content. They can also block Cookies.

Try setting permissions for our domain ( in your Firewall. if you can run the "Learn to Play" applet, then allow "Cookies". Otherwise, allow "Active Content".
