As with another recent update (I think it was v11.5.1, but I'm not certain about that), Microsoft has again managed to break Excel relative to the previous version. This time, Excel v11.5.4 displays a prompt stating that it is unable to save the AutoRecover information, and gives me the option of choosing not to repeat the prompt again. But it doesn't matter whether I want to repeat it or not, because clicking on the "OK" button that dismisses the prompt is useless; it doesn't work. No amount of clicking, or hitting any combination of keys will get rid of the prompt. Meanwhile, the current document is grayed out, as are menu functions...including Save. The only way to restore normal functionality to Excel is to force quit the app.

Naturally, that means that every bit of work I've done since the last time I saved will be lost. Nice Smeagol...er, I mean nice Microsoft; always helps!

I have no way of knowing whether this is some kind of an anomalous behavior of my particular instance of Excel, or whether it shows up for other users. If you haven't run the updater yet, be advised that v11.5.4 is already problematical for at least one user. Too bad; in general I love Excel. I use it daily, and I'd be lost without it. That's why it's such an irritation when Microsoft breaks it.
