When a book is in a floated panel & I try to highlight a section, immediately upon clicking on the highlighting option I want to use (say Blue underline), having selected the text to highlight first, the floated window is sent behind the main Logos window & the highlight command fails.
If I dock the window I want to highlight, then the highliting works.
This prevents highlighting in a larger, floated window where more of the book's pages can be seen at one time.
