Browser Issues for Window Users:


Note to Windows XP Users

By default, the Windows XP operating system comes with the Internet Explorer 6 browser without the Java Virtual Machine (JVM) installed.

However, if you install Windows XP over an existing installation of Windows that already has Internet Explorer with a JVM installed, then you should be ok.

If you do not have the JVM, the first time you try to load a Java applet you should be prompted to download the JVM from Microsoft.



Steps for Windows XP users with Browser Freezing issues:
  • Step1: Download and Install the Java Virtual Machine - (click here)

Firefox - What is it, and how to get it
  • Firefox is an alternative browser that is becoming more and more popular among Internet users.  It offers more protection against spyware and viruses, since it asks the user about installation of foreign objects.  It is open-source, meaning that outside developers can write addons or fix bugs that are found, and the issues can be resolved more quickly.
