Excel XML - Excel Crashes
 

We have created a web application that allows users to generate Excel
documents. We use Excel XML to create the document and allow users to open or
save the document. This all works fine. The problem occurs after the created
file has been opened on the users' computer and stays open for a while. Every
now and then Excel crashes. Excel also crashes when the user tries to Save
As.. the document.

Does anyone have any suggestions as to why that occurs.
