You will need to feed us a little more detail, you shouldn’t have any issues, the adminbar works fine on 3.01 and 1.2.6.

You need to tell us if you are using a child / custom theme and if so revert to standard bp-default to see if the problem persists if not then problem lies with the child theme.

Have you any plugins running that could affect things? Same principle disable any plugins other than BP to test whether it’s a plugin issue.
