Hello, I have Office 2007 running on a Windows XP P2 PC.

When I use Track Changes in Print Layout view, typing becomes very slow.
Ditto when I use Comments. Holding the left arrow key, for example,
causes the cursor to move only intermittently. Typing in the comment is
similarly slow; even when I'm typing fast, the text appears slowly on
screen.

If I close the file and reopen it, however, the problem goes away. If I
use Track Changes again--or add a new comment--the problem reappears.

Does anyone know of a fix for this problem? Thanks.
