Effecs files, parameter drag and wind....

Hi,I've read that the parameter drag in an effect file defines how wind and gravitation has effect on the defined particle.But even with storm, I can't get smoke to become horizontally. (if I use -3,-3, or -100,-100, ther'se no difference). There is indeed a slightly change in direction, but not so much as i want to define.Anyone an idea how to resolve this?reagrds,Johan Calj
