James, there seems to be a script conflict with http://wordpress.org/plugins/front-end-editor/ causing the admin bar toggle to break. I'm not sure about this but it seems to me that the Aloha editor's jQ Easing swing extension is the culprit (ref aloha.js around line 26500). I guess a quick fix in the Admin bar toggle plugin will be way faster to implement.
Since aloha's version of 'swing' doesn't seem to play nice with your script, a simple workaround can be achieved by explicitly specifying the easing function 'linear' for all animate()'s in the Admin bar toggle script, thus avoiding the use of 'swing'.
Thanks for your work on this very useful plugin!
