@apeisa: using IE9, I'm seeing a whole bunch of JS errors when loading edit views with Adminbar. Not every time, but couple of clicks on the edit button and there they are. Any idea what could cause this?
SCRIPT5009: 'Array' is undefined

CKEditor could be part of the answer, as this is one of our first big sites with it enabled. These errors don't show up when loading same modal edit view in it's own tab/window, so I'm guessing the iframe embed might have something to do with this too.
Also: in IE9 this seems to stay at the level of ton of errors, but a client has reported that on IE8 whole view simply freezes and nothing works. Again, not every time, but often enough to make it an issue.
Edit: actually this also seems to disable most features (links, lists etc.) in CKEditor (IE9.)
