I’ve few hrs back upgraded to WordPress 2.1 and came across a post WLTC, did you know there are more options there in WYSIWYG editor than what you first see? Thanks to this fourm support thread.

Just hit alt-shift-v (Firefox) or alt-v (IE) to toggle it.

(Not seeing either of those? Visit Users → Your Profile and make sure that “Use the visual editor when writing” is checked. Still having problems? Visit the WordPress support forums.)
