Basic Lightning and disable shadow for a material

Ugh, trying to replicate the issue I've found what was wrong.

I should have verified everything again before jumping to conclussions.

I'm very sorry for asking something that was incorrect on my part.

-----Please dismiss the incorrect question. Sorry.

I'm using basic lightning for this as the computer I have available right now is so old it can't manage advanced.

With that handicap I'm having this situation:

Let's say I have a wall and a window in it. I have a wall material and a transparent window material.

As the window is unpassable glass it has collision but I don't want it to cast shadow. So in the material editor I enable disable shadows for that material... but it still makes shadow even if I re-light the scene or save and reload the mission.

I would want that for invisible walls, too.

Am I doing something wrong, is it just a limitation of basic lightning or is it suppossed to work and something is buggy?

Thanks for your help.

Can you post some screenshots? Bit easier to have an idea of graphical problems that way.
