Gray WordPress log-in menu

Hi,

After updating to 3.3.2 the gray log-in menu (like wordpress.com) no longer appears on the outside of my multisites. It does after I’ve gone to /wp-admin, but many of my users are lost without it at the top.

Is there a checkbox I unticked? I used to remember seeing an option for this in the single user version, but can’t find it on Multisite.

I’ve looked through the forum and Web and can only find references to the Appearance > Menus or a log-out plug-in.

Any tips would be appreciated.

Thanks – Tom
