```
      Setup has detected that the newest versions of Internet Explorer
      components are already installed. Click OK to exit Setup without
      making any changes.

Additionally, the following issues in Internet Explorer 4.0 or 4.01 are addressed in Internet Explorer 4.01 SP1:

If a Web site uses a cookie with a 2-digit year of "00," Internet Explorer recognizes the cookie as expired. As a result, Internet Explorer behaves as if cookies have been disabled when visiting the web site.
NOTE: Cookies with 4-digit expiration dates, or expiration dates before and after the year 2000, work correctly.
For additional information, see the following Microsoft Web site:
```
      http://www.microsoft.com/year2000/ 
```
If a Web server communicates a 2-digit year of "00" in its HTTP/1.0 header, Internet Explorer recognizes pages on that site as expired. Although it caches them, they may expire earlier than expected. Browsing the site works normally while you are connected, but the site may not be available for offline browsing. HTTP/1.1 headers, headers with a 4-digit year, or headers containing 2-digit years before and after the year 2000 work correctly.
For additional information, see the following Microsoft web site:
```
      http://www.microsoft.com/year2000/ 
```
If Microsoft Wallet is installed, Internet Explorer does not allow the addition of a credit card with an expiration date in or beyond the year 2000. Wallet also does not allow you to add or edit your credit card information if your computer's date is in or beyond the year 2000.
For additional information, see the following Microsoft web site:
```
      http://www.microsoft.com/year2000/ 
```
When you are running Microsoft Outlook Express, you receive an invalid page fault (IPF) error message in Kernel32.dll when you are downloading news messages and your modem disconnects.
You cannot print from Internet Explorer or Outlook Express after you log off and then log on again. If you print a Web page or HTML message from Internet Explorer or Outlook Express, log off, and then log back on without rebooting, you cannot print from any program until you restart Windows. Print jobs remain in the print queue or the print queue is paused.
In Microsoft NetMeeting, the maximum capture frame rate is incorrectly kept below 17 frames per second (fps). On high-bandwidth connections, the highest frame rate is approximately 17 fps. The maximum frame rate is now approximately 30 fps. Results will vary depending on your hardware configuration. For example, a Pentium Pro or Pentium II processor is required on both ends to achieve 30 fps.
