Applies to:

• Autodesk® Design Review 2009 Service Pack 1

Known Issues

• From within Design Review, the Save As command requires the open file to be saved as either a DWF or DWFx file. Externally, the SaveAs API does not have the same requirement, allowing files to be saved with any file extension resulting in a potential security issue. Solution: Apply the Autodesk® Design Review 2009 SP1 Hotfix.
• Rapidly switching between Design Review and other programs may result in an EModelViewer error message, causing Design Review to stop responding. Solution: Apply the Autodesk® Design Review 2009 SP1 Hotfix.
