[openbox] Custom wallpaper not fully restored after a crash

[Luciano ES]

I don't like wallpapers. I like a solid black background.

During bootup and login, I get to see the Debian wallpaper, 
but it's replaced with my solid black background as soon 
as my session starts.

Sometimes though (and rarely), the Openbox environment or 
some part of it crashes. Then it behaves funny. The task bar 
may disappear or some other problem.

I decide to log out and fix everything. Or sometimes I need 
to log out and start a new session for some other reason.

In such circumstances, the solid black background is restored, 
but like a slightly short curtain, such that I can see a small 
part of the Debian background at the bottom of the screen.

I've never been able to fix that except by rebooting 
altogether.
Is there another way?

TIA
