Particles over the logo

I am not able to get the particle of smoke over the logo of Menu, the particle goes behind behind where it should go over … anyone know how to change?
Sorry for bad english…

First of all try to switch to 3d view and check that all of your object within camera box.
Then if you try to mix 2d sprite object and particle then you can adjust sortingOrder number

here is a script which will help you to do that, because of this feature is unavailable in editor right now.
