Difficulties with default a/c

Good morning... I'm fairly new at using FS9 and still struggling with the nuances.I thought I followed the steps outlined in another thread from yesterday in order to open up the Flight1 PC-12 cold and dark. But I did check the "make this the default" option.Subsequently, as would be expected, everything I chose opened cold and dark with two additions. Start up goes well, either in the individual sophisticated aircraft or using Ctrl-E, but here are the two things I can't seem to fix.1) The two red lines of script for F/R, alt, etc., which I almost never use, are on at startup, and2) Whenever I pause the sim for any reason, upon returning to the sim the engine quits.I have returned to the Cessna 172, running and parked, and saved it as the default but the two items listed above continue to occur for each flight.Am wondering whether leaving the PC-12 condition lever in the idle cut-off position affected all aircraft, and if so, after making the 172 the default, running, why all aircraft engines quit upon "pause".Would someone kindly give me a hint as to where to begin to look for the problem, and possibly how to fix it?I appreciate all the generous hints given by those on this forum.
