Using Logon XP

Most of the time when i try to edit a premade logon (e.g White System) in the logon studio. The log on is always represented pretty crappy in the editor. The user menu looses its place, the frame wont be displayed at all, and the buttons get crappy. Even when i dont change anything (e.g background), just to click on edit (to see how its done) and than hit save and apply, the whole thing is out of place, and lost graphic quality for the user menu.

How does this happen. Are those Logon`s made with Logon XP or Logon Vista and than resampled to Logon Xp?
