I presumed Calibre was opening ebook-viewer.exe when a book is opened from within Calibre, but I just noticed that if I open a book link in Calibre and look at what programs are running there's Calibre.exe and Calibre-parallel.exe running, but no ebook-viewer.exe, is this why I'm getting the default viewer settings when I open a book from within Calibre but if I open ebook-viewer.exe from within the calibre folder I get all my settings, theme and background image? I think this happened on the last upgrade, before that they were the same both ways.
