delta drivers lag problem

I’ve been using the delta drivers (.27) for a while now. Recently I noticed that when recording, the newly recorded tracks were “lagging” the previously recorded tracks. After doing some research I found these two links that explain the problem in more detail.

The problem exists using delta drivers .27 and before. I noticed the problem in n-track v3.3 and haven’t tried/tested in v4.

I will be trying the newest delta drivers (.5051) in the future to hopefully cure the problem. Maybe someone can confirm the newest delta drivers eliminate the problem?
