Why does the screen background picture get reset to default when switching user
iMac with OS X 10.6.8
I have several user accounts on this iMac, each with a different wallpaper chosen from a common folder (library/desktop/nature) in the top level of the hard drive. (Which exists – can always reset background picture from this folder)
When I switch from one user account to another, the wallpaper picture, set on the previous login, appears for a moment and then is immediately replaced by the default blue.
This happens when switching from any user to another. I tried restarting the system but the problem is still there.
This problem just suddenly started and there have been no upgrades or changes to OS X.
Ideas appreciated!!
