I am having some problem in saving a workbook.

I have an Excel WBook which uses the addIn. When I close the WBook by
clicking on the cross btn on top right side, it prompts to save the workbook
with Yes No and Cancel dialog box. When I click on Yes, it executes the code
which is written in the addIn during save event which save my workbook. After
saving the workbook, it again prompts the Yes, No and Cancel dialog box which
I need to get rid off.

Help would be appreciated.

Thanks

VJ
