I have a strange bug with the dashboard on one of my blog running svn version onf WP.
On the last line (578) of quicktags.js I have cont wich is null so cont.parentNode.insertBefore(tb, cont) does nothing.
It happens only on one blog, the second one is ok (same revision).
The result of this bug seems to be a non working ajax dashboard : I can't close neither move any of the items and the option menu is not working (un-checking options does nothing).
The third thing is none of the 4 last items are loading ...
I checked server-side errors : nothing.
I really don't understand where does this come from.
