Have started using Book module.
I notice that the return carriages between paragraphs do not always separate paragraphs. - Instead paragraphs usually display stuck together.
When I go back in to the chapter it takes two or three repeated return carriage strokes between paragraphs to separate these. Sometimes the paragraphs do not separate at all.
There may be a bug here. If so, where would it be best to report it? It may be that this is a TinyMCE and not a Book module issue. It could alternatively be an issue with the 'Formal White' theme I am using.
