transparent blended textures

[alex25]

if i have a couple of stacked transparent objects shouldn't they both show up blended on the background texture? i was looking at the starting grid at montreal and i noticed the starting position doesn't display because the skid marks are on top of it. the skid marks get blended onto the background asphalt texture but i would expect the grid marks to show where the skids texture is transparent which is not the case. i think this is a bug (and i don't know if it ever used to work).
