FCKeditor doesnt renders "<" and ">" properly

Im trying to create a documentation website where I store all my frequently used code and important conversation.
I installed FCKEditor so that I can easily highlight important lines but came across a strange bug.

When I paste IRC log lines into the body of the page and try to view the page, all the line breaks are ignored and the whole conversation is show as a single huge blob of text. Its only when i remove the "<" and ">" in the nicknames the content is displayed correctly.

Hope this can get fixed. I would hate having to replace the brackets each time I want to save some IRC chat.
