willywonka's post in Semi-unresponsive plane? was marked as the answerI think I've solved the A/P. If you're curious: it was the BIOS clock failing to keep correct time. I've corrected it (somehow) and with a working and correct clock, the NGX flies smoothly. There were a lot of reformatting, cussing, and drinks on the road to solution (I'm sure you understand).
I can't imagine what impact the clock has on FSX and its addons, but, there it is.
