Damn - another fine theory down the drain - LOL
It would appear the bug is real however - it's just the exact mechanism
we've yet to pin down.

Hey John,
Just noticed you seem to be transmitted a valid email address in your
newsgroup postings - probably wise if you 'mangle it' or in some other
way obscure it, lest the SPAM harvesting robots find you

I have been letting the system finish loading stuff & settling down
before logging in & I have not seen the problem since. Interesting???
Doesn't part of the registry get copied to a user specific part? Maybe
logging in to fast before it is copied due to a busy system causes
windows to grab the default wallpaper which I think is winnt256.bmp.
Just a thought.

Hi Bob,
I'm glad to see my 'remedy' works for you Not ideal I know, but it
will do for the moment.
I'm not sure what is really happening here as to WHY the wallpaper
doesn't load - you are right however, the .default user wallpaper is set
to winnn256.bmp, so this probably how we wind up with it on our desktops !
The way the profile situation works is that the hive ntuser.dat from
your profile folder (eg: D:\winnt\profiles\username\ntuser.dat) is
copied into the registry tree as HKCurrentUser during a login, but the
weird thing is that all the other elements of the profile ARE working,
(ie: you start menu, you desktop icons and layout), so I'm left thinking
that the registry is correct, and it is the loading of wallpaper itself
that fails.
The other (vague) possibility is that when the HKCU registry is 'read'
to determine what wallpaper has been chosen, this key read fails,
producing the same results.
I'm certain it is a timing issue in any case.
The other weird thing is that this only seems to happen on SOME
machines, and I've never been able to see the element of commonality
linking them to cause this bug. (For a while there John's theory of a
wallpaper folder of other than \winnt looked promising, but you shot
that one down in flames !)
