When editing in HTML mode, CuteEditor will insert extra line breaks - even though those breaks do not matter but it just driving me crazy. It doesn't happen all the time but most of the times it does (especially after postback). After switching between Preview and HTML those extra breaks are gone and HTML code is reformated but nevertheless it seems to be a bug.

 

Another strange behavior I have noticed is when I first time hit "Enter" in HTML mode, font size and style changes.

 

All of those behavior do happen on provided examples.
