An error occurred while saving the commentSimon Rawson commented
The SharePoint Properties opens automatically if the Content Type setting Always show document properties on open and initial save for this content type, is checked. I'd be happy enough if this worked and properties could be consistently displayed. All too frequently I get the No SharePoint properties found, error in Word etc, even when you can see the properties from the File->Info properties panel (which is unusable).
Some equivalent should apply for the browser version as well.
