Just tried that - still crashed even using the 800x600px version - which is waaay to small for iBookstore I know. I don't think it's the size - it doesn't even try as soon as I attempt to add an external fle - the message is "sigil a multi-platform ebook editor has stopped workingA problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available.
This happens even with an new empty file
