new material slots not cloning?

I’m sure when I used to click the + to the right of the material list, it would add a new slot and would use the data of the slot selected when I clicked it, therefore making both slots link to the same material. But now it’s just making a new slot with no material associated with it.

Not really important, but I’m sure it worked that way yesterday and somehow it doesn’t now. Does anyone know why?

maybe I dreamt it

That is how it now works in blender 2.5x

Don’t drink and blend, then, I guess

Thanks for the response!
