You cannot view a Web page that was saved from PowerPoint by using Netscape Navigator or Internet Explorer 3.x

If you save your Microsoft Office PowerPoint presentation as a Web page by using the default save options, you will not be able to view the Web page using a Netscape Navigator or Communicator 4.7 or earlier browser, or a Microsoft Internet Explorer 3.x browser.

The Netscape 6.x or 7.x browser may allow you to view portions, but not all of your Web presentation. In particular, some graphics and shapes may be missing. Animations may not behave as expected.

When you save or publish a Web presentation in PowerPoint, the file is saved in Hypertext Markup Language (HTML/MHTML) format, which is optimized for Microsoft Internet Explorer 4.0 or later. This format provides the best fidelity, fastest performance, and smallest file size.

Although Netscape 6.x and later does support many of the same Extensible Markup Language (XML) capabilities as Internet Explorer, it does not fully implement all of these features. If your Web presentation will be viewed using any version of Netscape Navigator or Microsoft Internet Explorer 3.0, follow these steps to allow your presentation to be viewed by any browser:

1. On the File menu, click Save as Web Page, and then click Publish.
2. In the Publish as Web Page dialog box, click All browsers listed above (creates larger files).

NOTE: If you have any version of Netscape Navigator, Netscape Communicator, Netscape, or Microsoft Internet Explorer 3.0:

• You first receive a warning page with the following text:
  This presentation contains content that your browser may not be able to show properly. This presentation was optimized for more recent versions of Microsoft Internet Explorer.
  If you would like to proceed anyway, click here.
  This page is included automatically when you create your Web site with PowerPoint 2003 or with PowerPoint 2002.
• Animations, including slide transitions, are not supported (except animated GIF pictures).
• GIF pictures might not be animated if the presentation is saved with a Screen size setting of 640 x 480 or less. (On the Tools menu, click Options. Click Web Options on the General tab, and then click the Pictures tab.)
• The slide is not scaled to fit the Web browser window. It stays at a fixed screen resolution based on the Screen size setting that you selected when you published the presentation. (On the Tools menu, click Options. Click Web Options on the General tab, and then click the Pictures tab. Adjust the Screen size setting as necessary.)
• The presentation cannot be viewed in full-screen mode.
• You cannot open or close frames.
• The active slide title is not highlighted in the outline pane.
• The mouse does not highlight elements in the outline pane.
• Sounds and movies do not play.
• Some graphics do not look as good as they do in Microsoft Internet Explorer 4.0 or later.
