In most cases this might be a compatibility issue in the Office 2003/2007 system.
In Office PowerPoint 2007, compatibility mode disables functionality that cannot be rendered with an adequate level of visual fidelity or editability in previous versions of PowerPoint. This ensures a consistent presentation experience across different versions
Office PowerPoint 2007 can add many new effects and attributes to content that are not supported in previous releases. For example, Office PowerPoint 2007 provides text effects for shadows, reflections, bevels, and other effects. Because previous versions of
PowerPoint cannot render this content, Office PowerPoint 2007 represents these effects as images in compatibility mode. If edited in a previous version, the image is “flattened” into a single object, instead of multiple objects. In addition, some
colors might render differently in previous versions. With the new feature refresh technology in 2007 Office system, even though these effects are saved as images in compatibility mode, they are once again treated as the original text effects when re-opened
in Office PowerPoint 2007.
