Dominick,
Thanks for the response.

I use temp cookies because I use code like this:
Web.Security.FormsAuthentication.RedirectFromLoginPage(UID, False)

I think it is related to spawning a 2nd browser session from the first by
using Ctrl-N.
In this case the 2nd browser instance "inherits" the in memory cookies from
the first.

The users were using a link to an Intranet site - maybe this link had the
same effect by spawning a 2nd instance from the first somehow.

I guess what I don't understand is how they can close all browser instances
and then click this link and still bypass the log in page. If the cookie is
temporary and in memory, isn't it destroyed when browser is closed?
Or is it really stored on disk somewhere until it expires? (I could not find
it and a re-boot makes it disappear.)

Thanks for any more input.
