Do not know exactly how to classify these.
I have been noticing lately that there are strange pop-up windows as I am reading.
For example, I am reading through the Life of Christ.

This window is from an earlier section of the book. It was saved at that point earlier, and then it somehow comes back in the pop-up window.
Also, in studying Romans 7, I got a pop-up for 1 Samuel.

I used this layout earlier when I was studying 1 Samuel. Now that I am studying Romans, I have saved my layout under the old layout name.
Again, I think that this is somehow coming from my saved layouts. It is like the program is remembering past positions in my saved layouts, and reacting to them.
This is my version number.

Blessings,
Kevin
