Firstly this application just gets better and better
When I click on the option to change my windows logon screen image (win7 Ent x64) - the preview shows the default windows logon image with my customized user profile picture. It does not show the custom logon image that I already have set using TweaksLogon.exe http://tweaks.com/windows/39468/customizing-logon-screen-background-in-windows-7/
The imapge is copied to the default location: C:\Windows\System32\oobe\info\backgrounds

Is there anyway the preview window can display the current logon background image - what ever it might be - if it has been customized by an oem or previous tweak, then show that image.

Not a high priority but looks like a defect in the preview.
