Strange Event With Open Book

cheez
 

I hope this is okay for this list.
Running Win 10, with latest version of JAWS and Open Book 9.
After scanning and reading a page, the field changes, as if I did an alt+tab.  So in order for me to get back to that scanned page, then I have to alt+tab for sure.
Does anyone have an idea on how to remedy this strangeness?
Now, I'm wondering if the new Canon LiDE 300 scanner I just installed has anything to do with this problem.
