    cd "program files\internet explorer - 4 compatible"
  4. Type the following command, and then press ENTER:
    iesqrl /3
  5. Type exit, and then press ENTER to return to Windows.

STATUS

Microsoft has confirmed that this is a problem in Windows 98 Second Edition.

MORE INFORMATION

When you install Internet Explorer 5 on Microsoft Windows 95 or Microsoft Windows 98, you can install Compatibility mode if you have already installed Microsoft Internet Explorer 4.0 on your computer. You can use Compatibility mode to run an Internet Explorer 4-compatible browser in Side-by-Side mode with Internet Explorer 5.
