This is the weirdest issue, I realize. I am running CB 1.7 on a Joomla 1.5.23 install. After upgrading to CB 1.7, site visitors running IE8 could no longer log into the site. They would put in their credentials and hit LOGIN, but the page would simply refresh without showing them as logged in. However, on the back-end of the site, I could see that they were, in fact, logged in.
I had a system canonicalization plugin installed and working fine for the past 18 months. However, following the upgrade to CB 1.7, I started noticing this issue. Disabling the plugin restores full login/logout functions to the front end IE users.
I am also running CB Subs 1.2.2.
