Last night I turned a Windows 7 laptop on for the first time in a few days and it decided for itself to download and install "Service Pack 1". Web searches suggest that that might allow IE10 (which I don't have) to use an optional spellchecker.
This may or may not be relevant !
I suspect that that is, indeed, very relevant, David. My machine decided, without a by your leave, to upgrade the browser to IE10 just the other day. So that's probably it, isn't it? IE10 doing it. I haven't noticed any other differences, apart from a slight change in look when you open a new blank tab.
