I have IYP running on my windows 10 machine. There are a few oddities, so I
thought I would install it on my Windows 8.1 box to see if it ran any better.
It worked fine on that box for a few days; but now, it suddenly doesn't work
anymore. I run IYP, the program loads; but after I run FSX and begin a flight,
IYP never does anything. Any suggestions as to how to begin troubleshooting
