Lorenzo,

Because Excel creates new Book with new bytes... so I think there will no
memory leak if Excel recognizes new book with the correct arrangement of byte

Hi Halim,

thanks for your post. I also think that the problem is due to memory leak,
but what's the advantage of creating a new workbook with the same contents?
