Hi all,
I posted this question some time ago, I would of summised earlier but was sick:

John Kohl came up with a solution, given below:

I have also got response from DEC who read this list as well and there solution
is similar:

Here is some observations I have seen with this problem as well:
With out fix:
-------------
Log in as ROOT. Move icons around background gets corrupted.
Log in as different user. Moving icons around DOES NOT corrupt background.
Log in as ROOT or different user, popping up menus corrupts background image.
With the fix:
-------------
None of the above occurs.
Thanks for all the help
