Using LogonStudio version v1.0.64 to apply my screens, I have been marginally successful at creating logon screens for an XP Pro SP3 machine. I have a few that others had made and discovered that they have developed a way to make a seemless screen, from top to bottom.  Mine have a line dividing the screen at the top and at the bottom. I was able to make bitmaps for all three sections, but can't figure out how to get rid of those lines.  I also had no links, when logging off, to get back onto my other accounts.  The boot screen has all three accounts, though they are transparent and I have to hover over them to get them to show up.

I do not have Adobe Photoshop.  I use Serif Photoplus 8 or Photoplus X2, if that makes any difference.
