I split this from another thread.
(Plus it's been far too quiet here of late.)
When this happens there are a group of Error Consoles messages that pop up.

NeilAway said (of the group) "probably a knock-on effect".
And "that's some sort of problem with the context menu trying to do spell checking", "doesn't know why that would fail though".
Fairly new occurrence.
Any possibility that it is NoScript related?
