Here's the situation, it's a bit a tricky...
A classic ASP application
User opens the IE browser to run the web app and then creates an instance of the web app in another IE window, sharing the same session and cookies. This causes some problems.
This there any way to do any of the following...
1) prevent user from selecting New File command in IE
2) trap the fact that this has occurred and start a new session or redirect the user to a login page
