That's what I'm assuming. I might go ahead and force it later if I have time to watch the action. Of course I've done this on a somewhat old build. I'd rather do it on a recent one, and I'm unlikely to get around to that anytime soon on this machine. > Is there any reason why this multi layering is even allowed -- seems > risky and hackish? Is this something that an administrator is likely to do accidentally or without understanding the consequences? Even though risky, is really useless in all situations? Otherwise, is it worth code to prevent it? -- Darren Dunham [EMAIL PROTECTED] Senior Technical Consultant TAOS http://www.taos.com/ Got some Dr Pepper?
