I cannot reproduce the issue with the attached DWF file in Autodesk Design Review (ADR) 2010 and 2011. I would like to know:
1. Whether this issue can happen on all of your DWF/x files?
2. Please open a DWF file without markup in ADR and save it as new file without markup. Whether 'File Save Failed' message can pop up?
3. Please upgrade to ADR 2011 and try again.
