Technical Requirements

In addition to the browser requirements already noted, this tutorial requires the following:

  • Cookies must be enabled if you want to be able to close the WBT and open it to where you left off. This feature does not cause information to be sent from your computer.
  • A minimum screen resolution of 800 X 600 (1024 X 768 is recommended)
  • Flash* Player 6 or higher from Macromedia*

    If you don't see an animation to the right, then you need to install the Flash Player from the Macromedia website at www.macromedia.com. If you do see an animation to the right, verify that you have version 6 of the player or higher by right-clicking on the animation. The popup menu should state the current version number. After installation, you may need to exit and restart your browser.

    Note: A known bug in version 6 of the Flash player plug-in may produce errors on Netscape browsers. Builds 40 and higher of the Flash player 6 contain a fix for this bug.


  • Note for users of 64-bit editions of Windows: The Flash player is not available for the 64-bit version of Internet Explorer. Use the 32-bit version of Internet Explorer.
