Error editing graph in PowerPoint 95 & 97 dual format file

If you save a PowerPoint 97 SR-1 presentation with an embedded graph in the PowerPoint 95 & 97 dual file format, open the presentation in Microsoft PowerPoint, version 7.0, and then double-click the graph object, you may receive the following error message:

This error occurs when you save a presentation in the PowerPoint 95 & 97 dual format. PowerPoint 97 SR-1 contains a new feature that converts Graph 97 objects to the Graph 5.0 format. However, you cannot use this feature with the PowerPoint 95 & 97 dual format. Because you cannot use Graph 5.0 to edit Graph 97 objects, you receive this error message. (Graph 5.0 is included with PowerPoint versions 4.0 and 7.0.)

To resolve this problem, follow these steps:

1. In PowerPoint 97 SR-1, click Save As on the File menu.
2. In the Save As Type list, select one of the following file formats:
   PowerPoint 4.0 with Graph 5.0 (*.ppt)
   PowerPoint 95 with Graph 5.0 (*.ppt)
3. Type a new file name.
4. Click Save.

NOTE: If you edit any of the graphs using Graph 5.0, and then reopen the presentation in PowerPoint 97 SR-1, PowerPoint automatically converts the objects to Graph 97 format. Repeat steps 1 through 4 when you save the presentation again.

This feature is under review and will be considered for inclusion in a future release.
