Used to get this on 6.0 periodically.  It is much more frequent on 6.2

I'm getting a null reference exception when I start my application which

uses ChartFX.

I do not get it every time.

Here is the stack trace. Do you have any idea what I should look for to

track this problem down?

My app is immensely complex.  There's no way i'll be able to repro it with a

small standalone case.

Do you have any experience with what sorts of "bad things" you can do to

cause this type of error so

i can check my code for spots CFX might not be happy with?
