BuddyPress.org

@hnla, and @xberserker, I figured out the culprit to this, but I am not sure why it does not take until 1.2.6 to happen.

The double button is because you have called 2 stylesheets from the same buddypress default.css. The most common mistake is the css from the bp template pack being applied, and than calling the same css from the bp-themes/bp-default/css/default.css. You need to remove one, and it should solve the double button issue.
