No, it's not a file.

When I'm working on a Word (2011 Mac) doc, a little later, if I drag the doc over, there's a duplicate doc, dimmed, with a spinner. It doesn't change, even when I try to click on it. And the page number is a few pages earlier. I have to close Word to get rid of it. I'm just afraid it may not save the doc if I leave it. This has never happened.

Another problem just came up; there's an "critical" update for Office 2011 Mac, which won't install, says I need OSX. I have the latest version, so what's the problem?

ACK!
