Thanks. Well, there must be something else going on. My first instinct was the same as your comments -- 161K shouldn't be a strain on a modern word processor.



I guess I need more instances of the problem to try to figure out the cause. I've only been using Word 2013 for a couple of months, and this is the first time I've noticed any problems.

Appreciate your time.

I'm seeing the same behavior in Word 2013 running on Windows 7 on a Lenovo T61p laptop. The file is a 177kb .docx file that contains both Tracked Changes and Comments. The slowdown appears to occur as soon as I open the Reviewing Pane or add a comment. The behavior consists of repeated frequent spinning circle machine-busy indications and grayed-out file-not-responding indicators. The only way to fix the situation is to close the file and Word down and reopen. But the behavior reoccurs as soon as I either open the Reviewing Pane or add a comment.

Best,
Alan

Almost exactly the same symptoms I'm observing. I'm using Win 8.1 and the subscription version of Office 2013.

Two instances isn't a people's revolutionary movement, but it suggests that my problems aren't just operator error of some kind. Maybe the next step is to make sure I can reproduce the problem on demand and call my friendly local MS office.
