BgInfo : Windows 7 Logon Screen Info

I am trying to change the default logon wallpaper to show the hostname of the machine.

The issue I'm having is that many of the users in my environment are using two monitors. When I try to create (and then apply) the lockscreen wallpaper I notice that it's trying to apply the wallpaper twice:

Does anyone know how I can resolve this issue? Under "position..." and then "Multiple Monitor Configuration..." I've made sure to choose "primary display monitor" but it doesn't make a difference.

Thanks!
