Thank you LiquidTension and exile360 for your many hours of interfacing between us customers and your gurus. As a tired old hardware developer I decided early on stay out of the fray and let those with far more software savvy run with it. And they did very well. Congrats to all. Personally I regressed to 482 mid December and still sitting on it. If all holds together until February I'll switch to 527.
But now that the fire is out and the smoke slowly dissipates, and everyone moves back into their comfort zone I find it interesting that many running only MWB had issues (like me), while others running only Avast or possibly another malware tool with or without MWB had issues. And I find your comment about "multi processors" having been affected by some MWB code in 508 really interesting. The problems people reported within 18 pages of this forum, to me ring of a variation/combination of Stuxnet, Spectre, and Meltdown aberrations.
Just FYI for the next time in white water.
