Smoke not showing up in Preview

I have blender 2.77 and trying to do a smoke simulation and it will not show up in my 3d view. It show up in render sometimes, but no every time. It would be very helpful if someone could help me.

hi jonathan,

could you create a new scene wit a cube. select the cube and hit spacebar. type in “quick” an select smoke.And make sure that your start frame is 0 or 1. press “alt+a” or click “play” in timeline. You should see the smoke.
