blender 2.55 r33274 Material Linking Problems

I have a problem I can’t seem to solve.
I am doing a typography piece so each word needs to fade in at different times but all the words have the same material. So I have a temp font object which I just copy and then edit for each word. In the past I have just clicked the number next to the material to make a single user object. But today it is not working for some reason.
I click the button and it copies the material and renames it but when I insert keyframes for the transparency it also keyframes the original temp text object.
Does anybody know anything or am I just on my own?
As in the title I am using 2.55 r33274, could that be my problem?

actually solve my problem :slight_smile: Just press the plus sign button next to the material name area to copy the material. Apparently that works!
