I don't know why this is so. If you are referring to an actual dolphin site with the latest version last time I checked I did have the "html" option to click on an enter html code for blogs. I didn't check events.

I often find if I use one browser it will do one thing and another does something else with the line breaks. Usually, which is kind of a pain to get line breaks. I type what I want to say in notepad then copy it and paste it with firefox web browser for forums and such, then see more the line breaks work. I do not use ie7 so I couldn't say how the line break works with it.

The blogs here where I am writing this line breaks seem to work directly by writing in this post a comment section.
