I'm using Calibre portable so I can use it on my desktop pc and my tablet that I read on. When I try and set any file associations - for instance for epub's or mobi's - windows 7 wont do it, is this intentional because it's 'mobile'?
Also I seem to have two different themes for the viewer, one when I open a book from within Calibre's main program and a different one if I open ebook-viewer.exe
