@serpentine - the sooner the better to give us a chance to fix it before the next beta release. Don't worry about diagnosing it yourself just send it through and we can all do it in parallel. If it doesn't happen for us with the whole file a smaller one won't help

@mrmikel - thanks, I understand now. I don't see an easy solution to keep everyone happy. Sigil 0.5.3 had a behaviour we deliberately removed for 0.6 where it used to open the next file after a delete. It (a) drove me insane (it was like playing whack-a-mole) and (b) happened to be the cause of one of the most common crashes in 0.5.3 on Windows. Just hit Enter after you do a delete, and your next tab will open, job done
