If you're running the store from a URL consisting of an IP address instead of a properly named FQDN then I'm not surprised that you're having session problems. Change to a proper FQDN and it'll work much better. Since you said you're using a virtual machine, I suspect using "localhost" will probably work a lot better than using 127.0.0.1
new 1.5 install last week, on a server that 1.3.9h is working fine on.
Admin was working great for 3 days, than all of a sudden I can no longer log into my admin. I have tried IE 9, Chrome, and FF and the login page just flashes and refreshes. I get the email "Admin login failure notice" and password resets are not working either.

Any help with this?
