Blogger hates me.....

I have been trying most of the week to add some HTML and javascript code to a blog. It looks OK in the edit window but every time I save it, Blogger destroys my beautiful javascript code... It tries to format it, moves fragments of code around and destroys it completely. Escpecially special chars (including the not so special " and ' chars and whitespace!!!) seems almost impossible. I have spent several hours of my precious spare time on this.
