Word has encountered a problem. You will not be able to undo this.

[PJ]

A client gets this dialogue box when inserting a comment into a Word 2003
document when using Word 2007:
"Word has encountered a problem. You will not be able to undo this action
once it is completed. Do you want to continue?"
The choices are "Yes" or "No"
OS = Windows XP pro sp3; Office 2007 sp1. The original document created in
Word 2003 being edited in Word 2007.
