I plan to, but you know the old saying: "Better have all others think you are a fool, than open your mouth and remove all doubt." Family problems have delay my response. I am collecting some sample code and explanations to show what I am seeing. Also I testing and removing some bugs in my own code that may account for some of the problems I have seen. One thing, I seem to have random crashes if I have a static array that is greater than 256 MB inside my driver.
