Mat IPO in scenes

Hi, I have an issue with MAT IPOs 2.48a, might be a bug.

I have an object (cube) with a basic colour (blue), the object appears in scene 1 and scene two (scene 2 created by add new scene / link objdata).

In scene 1 I have animated the objects colour to fade out using alpha.
In scene 2 I want NO colour animation, so I create a new matipo and remove the ipo curve, but this new ipo is also attached the the cube object in scene 1.

I want 2 individual matipo’s for each scene for the cube.

Can anyone help - thanks Andrew.
