Chess Magnet School Troubleshooting

If the Training Room 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 Training Room, follow the steps below.

1. Get the Right Browser

The "SBC" or "Yahoo" browser does not work with Chess Magnet School.

We recommend the Firefox web browser which is a free download here:

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

2. Get the Right Java

Using Firefox, or your chosen web browser, 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 Java installed.

If you don't have Java, click "Free Java Download". On Vista, you need to save the file, right-click and "run as administrator".

3. Let Your Browser Use Java

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

With Chrome, there is generally nothing you need to do.

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".
