I make smoke rings and to do that I need to release 40 particles once at one time. This has worked for years now but the WinLight viewers have brought tons of customers to my store complaining. I've reproduced the problems and tried many techniques to get around it but have not found a workaround. I have other effects that also release multiple particles and these are affected as well. Here is the code I use: llParticleSystem([ //-------------------------- particle definition PSYS_PART_START_COLOR, <1,1,1>, PSYS_PART_END_COLOR, <0.3,0.3,0.3>, PSYS_PART_START_SCALE, <0.032,0.032,0.0>, PSYS_PART_END_SCALE, <0.25,0.25,0.0>, PSYS_PART_START_ALPHA, 0.8, PSYS_PART_END_ALPHA, 0.0, PSYS_SRC_TEXTURE, "2ca57748-4944-de53-b301-8d0efbafb2c6", //-------------------------- emitter definition PSYS_SRC_BURST_PART_COUNT, 40, PSYS_SRC_BURST_RATE, 15, PSYS_PART_MAX_AGE, 10, //PSYS_SRC_MAX_AGE, 0.5, //-------------------------- particle placement parameters PSYS_SRC_PATTERN, PSYS_SRC_PATTERN_ANGLE_CONE, PSYS_SRC_BURST_RADIUS, 0.01, PSYS_SRC_ANGLE_BEGIN, PI*0.03, PSYS_SRC_ANGLE_END, PI*0.03, PSYS_SRC_OMEGA, <0.0,0.0,0.0>, //-------------------------- particle movement parameters PSYS_SRC_ACCEL, <0.0,0.0,0.02>, PSYS_SRC_BURST_SPEED_MIN, 0.3, PSYS_SRC_BURST_SPEED_MAX, 0.3, PSYS_PART_FLAGS , 0
