2.61 No preview(-sphere) and other missing functions under materials button?

Hi guys,
Working in Blender 2.61, when hitting the materials button I’m missing a lot of functions like ‘preview’ ‘diffuse’ ‘specular’. I DO have this functions when I open 2.61, but in this project I’m working on, they seem to have disappaered. Is there a way to make them show up again? (In user preferences or…? Thx in advance!

I found out myself: It’s the diffence between Blender Render settings and Cycles Render settings… …thx anyway! :wink:
