Microsoft Office Web Component issue

[Ramesh]

I am using OWC11 in my application. My application functionality is to open
the Excel workbook.

I am able to open Office 2003 (Xml Spreadsheet) document using OWC11's
AxSpreadsheet object.

But the AxSpreadsheet show's last cell of each spreadsheet as merged column.
But my original spreadsheet does not contain any merge on last column.

I don't have any idea why this is happening.

Can any one had come over this issue?

Thanks in advance.
