Hi guys( and girls)

I got something strange, i download and installed udk dec. 2010 and when i add a CSG can't select ridge or corners in perpective view to move or scale the CSG but i don't see anything to make a selection. I would like have it just in wireframe mode but then with the texture's etc.

Have anybody an idea how you can activate this. (i know, stupid question :P)

thanks anyway.
