transparency for window glass ...

I’m trying to create a window for a house, however it doesn’t seem to work. I have added a cube and decreased the alpha to 0 but nothing happens. I’m so frustated as I was dealing with this since yesterday. Any suggestions?
Thanks…

Did you tick the box next to the left of the Transparency tab to enable transparency
Are you using Z transparency of Raytrace transparency.
If you don’t see transparency in the 3d view, do you when you render ?

Thank you for ur reply. The box is ticked and I renderd but nothing happens :frowning: … Anything else I could do?

You won’t generally see transparency in the 3d view unless you are in textured view and set the display to GLSL (needs a supported graphics card)

Everytime I try to click these my blender freezes :frowning:
and I have to restart my blender again. It stays like that (see picture) and I can’t do anything else …


Also I tried to render but that is the result I keep getting


Any suggestion? Thank you!
