first yes i definately did type shift+d and not alt+d, also i checked preferences and the options for duplication of textures and material are NOT selcted.
I am using fedora core 3 version, so either its a quirk with that or my preferences are not being taken into accout im using the 2.37 version for linux.
Though on the plus side its good to know about ctrl+U as before then i had to keep resetting the preference to off for textures and materials, even though it made no difference to duplicated objects they still were linked.

Yes you first point excatly duplicates my problem in that both objects are still linked materially. The single user button clinking i will try.
To slikdigit Thu Jun 16,
Yes i did read the documentation, its the very first thing i downloaded and
read. It may just be that different version of linux have blender set up differently but after duplication of a obj with my version the materials are still linked if i then add a new material from the material & textures button (the silly red ball picture) they are still linked but now i have a new material. Il try the single user thing.
On another point i, while i was about ready to commit suicide i decided to start at the very beginning of the forum and I found something that did work, Though im sure there is a good reason why this is not the right way to do it, may be someone could explain it.
A post i found said that if before i duplicate an object with shift+d that i make sure that im in object mode the materials dont get linked, while in edit mode they do. And sure enough when i tried it with duplicate done in object mode the materials arnt linked while in edit mode they are.
Now given what ya have all said, is this a bad way to do it, or should i try to get yours ways to work, as im wondering why no one mentioned it.
BTW im using BLENDER 2.37 LINUX VERSION with fedora core 3.
Thanks for all those that answered, now im off to play with the single user thing and report back.
