Decided to do a logon screen that fits to my JK-G5 wallpaper [link]
Here it is, enjoy
Its made for 1600x1200 but it now works on all resolutions
Version with windows flag logo can be found here [link]
You need to have ThemeManager [link]
or LogonStudio [link]
Both are from StarDock & both are free.
Edit 3009042000: Now includes "logonui.exe" and fixed the "white pixels" problem on lower resolutions.
