Well, I would suggest making a replicable case that prove the problem if you want the help. Based on the description you provided nobody can help you (neither charlessw) The problem could be somewhere in your code, in C#, in the tesseract, or even in your environment/OS... You observed the problem => you need to narrow down where is the source of the problem.
