Strange session behaviour in chrome

[eluser]phatphug[/eluser]
I've figured this out after lots of head scratching...

I have two installations of CI running, one on /public_html and another on public_html/development (so that dev work doesn't impact the live site)

This means when I visited /development, a session was being created in both instances of CI. Since both were using the same cookie name, this was causing havoc in Chrome/Safari (Webkit).

I've given each install unique cookie prefix's now to fix this.
