Ever since the latest update, while working in a book.indb file, if I open a file from the "book" then the "book" disappears from my panel. It's there if I go to Window, there it is listed. I click on it, the panel jumps up in the upper left corner of my screen, I move it back to my main panel on the right. I open a file, work on it -- book panel is gone -- and the routine starts again.
Is this a bug? Or??
Been reported already. Try moving the panel to a second monitor.
Thank you! (No second monitor. I'll live with it.)
