Hi Steve,

I'm somewhat confused, but I'll take a crack at helping as much as I can.

A web application is defined as a virtual root directory (a directory which
is configured in IIS as an Application), and all of the directories
underneath it which are NOT defined as applications. It sounds like your IIS
Application configuration is messed up. I would start by taking a look at
that.

Opening a browser window using JavaScript may or may not initiate a new
Session, depending upon the browser. I wouldn't count on it.
