Terrain Toolkit texturing broken in Unity 3.0 ?

This picture shows the Terrain Toolkit's procedural texturing sub-menu. alt text

Does anyone how to fix this?

I am having the same problem, all the terrains w/textures I built in 2.6 have transferred over but the tool kit is broken. So I cannot make any changes. Any help would be nice.

I have the same problem

Same problem. It is possible to change, to a terrain ok but the display is not working.

i don't see any problems with the texturing of the toolkit, i have one myself, and it looked just like that in unity 2.6.2 so i don't really know what's wrong.
