start-up and shut-down screens

[Brian]

I have had random photographs turn up on the start-up
and/or shut-down screens. What are the filenames for these
screens? Why do they change themselves? Is there a software
application that can change and control these screens? That
would be the answer!

Probably they are wallpapers you've added and then replaced. Right
click on the desktop, select "Properties", and the "Background" tab.
Set the wallpaper to "NONE" and click "Apply". Then select the
wallpaper you'd like and click "Apply", that should fix it.

Any time you want to change wallpaper, you must select "None", apply it
and then choose the new wallpaper.

It's a bug, I don't know how to fix it but the workaround is easy.
