Navigation bar; 'menu name' problem

Me and my fellow admin are trying to change the images on the navigation bar in Display > Headers and Navigation. We're able to edit the images for all of the links except 'New Messages/No New Messages'. When we click 'save' it says we need to add a "menu name" but when we try to add a menu name it won't let us type anything?

Any ideas?

Thanks in advance,
Scary.

Do you have screen shots? If not, which way did you use (choose one below):

ACP>>Display>>Pictures & Colors>>Pics Management

OR

ACP>>Display>>Homepage>>Headers & Navigation

We went the ACP > Display > Homepage > Headers & Navigation route.

EDIT: All is good! We tried the first route you showed and it seems to have worked! Thank you!
