Hi,
I think (not sure) I've seen this behaviour previously, but it is certainly present in the latest version.
Steps to reproduce:
1) open a book in two-page mode (haven't tested other ones)
2) switch focus to a different window (Chrome, for example), leaving Freda visible in the background on your screen
3) left-click on the rightmost page, simultaneously switching focus back to Freda and turning the page
4) left-right arrow keys no longer function
Going back to the shelf and opening the book again resolves the problem.
I'm on Windows 10.
