We received several slides in a PowerPoint presentation that are composed of more than one image, one of which is our consultant's logo. This logo appears in reverse and upside-down on the screen and when it prints, as if the image has been rotated 90 degrees on its X-axis. Everything else on the screen appears correctly. If we open the same slide on another computer with PowerPoint 97, the logo appears as it should. Any ideas on how to correct the appearance of this logo?
