Hi all. I am trying to edit an epub file using Sigil (v 0.1.9) and it just hangs constantly every time I do anything, i.e. insert a chapter break; five minutes later Sigil starts responding again. It's just unusable for me at the moment.
Now, I don't see anybody else having these issues, I think, so it must be something I'm doing wrong, or something wrong with my epub file (although I have tried it on a few different epubs with the same result).
Anybody have any ideas please?
