Was trying to replace all the bold characters with another format using replace all, but when I click it, it stops responding or its too slow to edit a 3 page document.

Steps to reproduce:
1. Open file and go to the find and replace window.

2. On find, go to Other options > Format > Font Tab > Style set to bold

3. On replace go to Other options > Format > Font Tab > Style set to bold, Size 18pt and then on the Font Effect tab change font color to orange.

4. Hit replace all and on the "To proceed with this action you must first turn off the "undo" function. Do you want to turn off the "undo" function?" click yes.

After that it will change the first instance and just stay there, non-responsive. Attached is the .docx file used on this report.
