When a DWG file is opened the embedded thumbnail is displayed in both the browser and viewer, but the full image can only be viewed if the required plugin is installed. This seems an unusual situation that can easily cause confusion.
It would therefore be useful if a message is displayed indicating that the plugin is required to view the file, and if possible providing the download link.
