Only particles that are labeld with a "S/W" will work in the normal rendering window. The S/W means "Software" rendering, which is the normal rendering method. For other types of particles, such as multistreak, you have to use Hardware Rendering. It is located under Window > Rendering Editors > Hardware Render Buffer or something of that nature.

It has its own Render Globals and everything.

The thing most people don't like, however, is that you have to composite the hardware render over the software render...

So, what you'd do, is render your scene normally in Software Render... Then, render it again in Hardware render with only the particles showing up (useing the Geometry Mask in the Hardware Render Buffer's Render Globals settings).

Then, in a compositing program, overlay the hardware render frames with the particles over the software render frames with your scene...

Complicated? Sorta.
Difficult? A little.
A Pain? You betcha. lol
