I'm not sure what you mean. I'm using SB6 #1750. Is it not Vista aware? Given what you've explained wrt a private win.ini, shouldn't the Clarion Detection item be modified to also look for the info where it would be for the currently logged in user, and for all users, when running under Vista?

One of my reasons for upgrading was for Vista support, but the current implementation seems quite unpredictable wrt the Clarion related items when running under Vista.
