PNG transparency problem


here is a very simple scene consisting in a simple 2D planar square made and textured in SketchUp with a PNG 24 bit image file with transparent background.
Whatever I try KT seems to have problem dealing with the transparency and I can't figure out why...
Alpha Chanel is checked in the Material Editor.
Also you will see that the texture preview (the small texture icon next to the diffuse chanel) looks weird.

As anyone allready figured this kind of problem and found out what the problem is ?

I must say that I often use PNG image files and that I never had this problem before...

Any idea ?

I found an issue with the use of a clip map but I don't understand why it doesn't work without.
Why using a PNG with transparency (alpha chanel) in the diffuse chanel doesn't act like cliping ?
