Excel hanging in task manager

Hi

This is not an aspose excel issue, but hope some Excel experts can help me here.

I am using aspose-excel generates excel report on our web site. It’s very clean for our server, which means no Excel.exe hanging on the server. However, on client PC, it opens excel sheet through a IE page, and excel.exe will still hang in task manager after client close the page.

How can I make excel end in client task manager?

Thank you

I don’t meet this problem in my place.

Which version of MS Excel are you using? Do you meet the same problem while running our feature demos?
