Determining the Scope of the Java Problem
To determine the scope of the Java problem, follow these steps:
Visit the following MSN Java Web site: http://zone.msn.com/bejeweled/ <http://support.microsoft.com/default.aspx?scid=http://zone.msn.com/bejeweled/>

If the Java program operates correctly, the problem is probably specific to one Web site. Follow the steps in the "Java Problems on One Web Site" section in this article. If neither of the Java programs operate correctly, the problem is most likely specific to all Web sites. Follow the steps in the "Java Problems on All Web Sites" section in this article.

Java Problems on One Web Site
If you are unable to view a Web site that contains Java programs, but are able to view other Web sites that contain Java programs, follow these steps to resolve the issue:

  1. Download the Microsoft virtual machine from the following Microsoft Web site:
    http://www.microsoft.com/java <http://support.microsoft.com/default.aspx?scid=http://www.microsoft.com/java>
  2. Visit the Web site that exhibited the problem, and test to determine if the issue has been resolved. If the issue has not been resolved, continue with step 3.
  3. Click Start , click Run , type control inetcpl.cpl , and then click OK .

For Internet Explorer 3.x, on the Advanced tab, click to clear the Enable Java JIT Compiler check box, and then click OK . For Internet Explorer 4.x, 5.x, and 6, on the Advanced tab, click to clear the JIT Compiler for virtual machine enabled (requires restart) check box, and then click OK .

Restart Internet Explorer and then visit the Web site that exhibited the problem, and test to determine whether the issue has been resolved.

WARNING: Using Registry Editor incorrectly can cause serious problems that may require that you reinstall your operating system. Microsoft cannot guarantee that problems that result from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, see the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Microsoft recommends that you back up the registry before you edit it. If you are running Windows NT or Windows 2000, Microsoft also recommends that you update your Emergency Repair Disk (ERD).
