It is harder to turn off scripting in Internet Explorer. Choose Internet Options from the Tools menu on the browser, click the Security tab, and check whether the Internet or Local intranet options have custom security settings. If either of them do, click the Custom Level button, and scroll down to the Scripting section. Check that Active Scripting is set to Enable.
A final point to note is how to open our code examples in your browser. For most of the book, you simply need to open the file from where it is stored on your hard drive. You can do this in a number of ways. One way in Internet Explorer is to choose Open from the File menu, and click the Browse button to browse to where you stored the code. Similarly, in Netscape Navigator choose Open Page from the File menu, and click the Choose File button; in Netscape Navigator 6, choose Open File from the File menu.
