Cannot closed Word because a dialog box is open

[Sesquipedalian Sam]

Internet Explorer hung up and I had to force it (CAD). When it closed,
Word was also semi-frozen. I had about 6 document open and I could
task switch between them, but the document windows were all blank and
if if tried to close them, I got an error message saying Word cannot
close, sorry.

Finally, I clicked End Now. Word came back to life, said it was
recovering, then seemed fine. I did not get a recovery panel.

I task switched to each document and did a save, which worked. Then,
when I tried to close any of them, I got the message above that a
dialog box was open. I minimized everything, but cannot find a dialog
box of any kind.

Any clues how I get out of this mess?

PS: An Internet search turned up several articles implicating Norton
AV. I am not running any Norton products and never have.

PPS: The hanging started when I tried to open a PDF document on a
website, so I sorta suspect Acrobat. It has caused other problems.

PPPS: I waited about half an hour and it did not free up. I still
could not close Word using the x-box, but I was able to close each
individual document using Alt-F, C. When I got down to the empty Word
window, I just rebooted. Windows forced Word, but no docuent were
open, so none were recovered.
