Gents,
I tried the idea that Martin.S suggested as soon as I found this post. RLBrooks your suggestion is pointing to the same idea BUT on my system it took me almost the whole day to implement due to the fact that I needed to do more housekeeping in my system. (thanks Sundog).
Also by just stopping there seemed like a short term solution and I really wanted to get right to the bottom of this (lol I sometimes go overboard )
So after optimizing my system, going back to basics so to speak and removing unnecessary add-ons and plugins the answer that worked for me was exactly the one that Martin.S suggested! The key to this whole puzzle, for me as with Martin.S, lies in NOAA.... DO NOT USE VATSIM AS THE SOURCE FOR WEATHER INFORMATION.
I tested my system with the NOAA plugin. RWC and xSquawkbox many times over and they all work together as long as the NOAA plugin uses NOAA as its source for the weather
Setting the METAR source back to VATSIM results in the SkyMaxx crash occurring again.
Since this change was implemented I have also not had a xSqauwkbox crash again
So if you are as stubborn as me, have fun, but this appears to be the answer for me.
Thank you one and all for your suggestions!
