Startup effect question

Is there a particular effect file that controls startup effects for most aircraft? I must've downloaded something as a part of another package, because now when I start up most of my planes, I get flashing red lights (simulating exhaust stack flames?) and smoke trails from all the engines for a good 5-10 minutes, even on jets! (Gotta love seeing a POSKY 747-200 with red blinking lights in all four engines and smoke poofs trailing behind!)Eventually the smoke trails go away, the blinking/flickering red light stays around a bit longer. It even shines through into whatever VC I'm using. I stuck a screenshot on here to show an example (using Milton's new Shrike Commander).Anybody got an idea of what effect file I should look for, or what to change in config files?http://forums.avsim.net/user_files/89540.jpgLewis "Moose" GregoryColumbia, South CarolinaDVA 1427/Solent 644
