I am having a problem with Aspose.Cells 126.96.36.199.
I have attached a Visual Studio 2008 console application and two .xslx files (one protected, one not protected) so you can see what is happening. The console application shows that Aspose.Cells.dll can properly handle unprotected Excel 2007 files from the file system and stream but it does not properly handle protected Excel 2007 files from a stream.
The protection I applied to the workbook is the "Protect Structure and Windows" where only the "Structure" checkbox is checked.
Please let me know if you find a solution for this, either in the Aspose component or in my sample code.
