2.6 Alpha not working?

I rendered some grass that i made with blender 2.6 I choose “draw image with RGB and alpha transparency” ( I can see the checker transparent background) I then save image as a png. When i open it in a paint program is has a solid image.


In the Render / Shading / Alpha setting, did you set it to transparent ?

You have to make sure you save the image with rgba settings also.
