Commented Issue: Seems Like there is a row and Column Number Constraint while generating an XLS file [11459]

I have generated few Excel files (.xls) files.

Files having rows > 10 and Columns > 12 are readable in ExcelReader(http://exceldatareader.codeplex.com/)

Files having rows or columns less than that have a problem in reading.
the Error while Reading is : "Error reading Workbook Globals - Stream has invalid data."

But ExcelReader is working fine and can read 3column 3 row excel file (.xls) file created through MsOffice 2007.

@tonyqus ExcelReader is able to read excel having 3x3 rows and Columns created in Microsoft Excel 2007.

But the Excel sheets made by NPOI if have the above criteria is not readable by ExcelReader.
So it is definitely a issue of NPOI.
