Blender Internal Smoke simulation

Hi ,

I notice that in blender 2.71 whenever I set an object to be a Smoke domain its “Maximum Draw Type” automatically changed to “Wire”
and due to that I can’t see the result in Rendered shading ( Blender Internal ) until change that value to “Textured” …
see the image below …
Of course this problem happen only in BI

Anyone have same problem ?!
