Hi everyone,Not sure if anyone can help me here - basically this has started happening for no apparent reason (none that i can think of - but thats not to say its not a PEBKAC error :) )http://forums.avsim.net/user_files/84098.jpgHave any of you seen these strange trails before - i thought it may be a fuel dump, but its happening on all AI planes as well - and I'm not convinced there is a global fuel dump? Payware, freeware, time/season location - all irrelevant in that the error still occurs; so, have any of you people here seen this kind of thing before, and even better, know of anyway to fix it??!Thanks for help in advance, Leo

I believe this has something to do with the effects of older add-on aircraft, what you should do is put in your FS2004 install cd (I believe it was nr 1 but not sure) And open the .cab file called MSGAME1.CAB in there you will see a folder called effects. In there should be 2 files fx_contrail_l.fx and fx_contrail_s.fxjust copy em both and put them in your FS2004 effects folder and that should do the trick :-) :-waveshocky :-hahEUROPE UNITED"Can you hear them? my 1000 words..."
