I want to load a protected workbook for readonly access.  The spreadsheet I have has a password for "Protect Structure and Windows" set.  This does not disallow the file from being opened, just from workbooks being added to the file.  When I try to load the workbook, I get the error listed below.  Is there a way around this?  Will this be fixed in a later release?  Attached is the file used(with the extension changed from xls to txt to allow uploading).

{"Attempted to read past the end of the stream."}
