I've been using Calibre for converting books into ebooks for about a month now. Both I and my colleagues have encountered a problem that's annoying but not devastating. I'm wondering if it's our fault or Calibre's. Occasionally when we open a book for editing, Calibre will not accept any keystrokes—anything from trying to enter text in an .xhtml or .css file, or even a "command + S" keystroke to save.

Oftentimes closing the file and re-opening it will solve the problem, but not always. Sometimes we have to close Calibre, and when that doesn't work, restart our machine.

Has anyone else encountered this?
