Closed 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.
