ImageDesigner was rendering un-necessary inline styles. This has been fixed now. By default no styles are output unless the options in the designer are set explicitly.
Font selection, format block, font-sizes etc were broken in IE due to an erroneous previous build. This has been corrected now and everything is working like a charm.
The spellchecker was duplicating content in the editor when activated. This has been fixed now.
Adding blockquotes was buggy in firefox. This has been fixed and improved. Now when inserting a blockquote or selecting text to blockquote, it breaks out of the paragraph if you made the selection or tried to insert a blockquote inside a paragraph ( Paragraph cant contain block elements, invalid xhtml) ; all fixed now and working nicely cross browser.
