@MAB-Tech There is too little information to assume anything.
Please answer the question, or better yet, attach the project that is causing the problem to the forum's private messages.
For multithreading you should use resources. There are additional
settings for each resource, just double click it inside resources pane.
There you can fine tune your settings to achieve desirable behavior.
In your case you should set resource to use each line only once,
and set max symultanious usages to 1. Check other settiings too
to make it work the way you want.
