Ok....Here my issue. When Im viewing the fire/smoke/whatever i've made in the main timeline window.....it seems like the particles don't die off like they're suppose to. They seem to pile up. and eventually become one long streaks on the background. I checked the files when I render them out to pngs, etc......i get the same effect. But when Im viewing the particle emitter in the Properties window.....the emitter works great. the particles die off etc.
I've given some links below to illustrate my problem.
