Interactive button not work running 7.0 presentation in 4.0 due to 4.0 sav.

Cause:

The presentation was saved in PowerPoint 4.0 format

Solution:

Do not save a PowerPoint 7.0 presentation that contains interactive buttons in PowerPoint 4.0 format.

NOTE: Interactive buttons created in PowerPoint 7.0 using 'Interactive Settings', to branch to other slides or presentations, lose their interactivity when the presentation is saved in PowerPoint 4.0 format. Only the graphic itself is saved, WITHOUT the interactivity.
