Fix Word for Mac Freezing When Reviewing Pane Opens in Large Documents
Question details
The user experiences performance drops, freezing, and forced switching to the Reviewing Pane when editing large Word documents on a Mac.

- Product
- Microsoft Word for Mac
- Device & OS
- macOS
- Scenario
- Editing a complex document with numerous pending revisions and lengthy comments in Page Layout view.
- Observed behavior
- Word automatically switches from the Navigation Pane to the Reviewing Pane, causing the application to become slow, freeze, or make comment responses impossible to edit.
Ensure that your macOS and Word for Mac are updated to the latest versions, and save a backup copy of your document to prevent data loss before troubleshooting.
Switch to Draft View to Reduce Display Overhead
Using Draft view prevents Word from trying to render complex page layouts and lengthy comment balloons simultaneously, which is the primary cause of the freezing.
In Page Layout or Print Layout view, Word attempts to display comments in margin balloons. When comments are too long or numerous to fit within the page boundaries, Word automatically forces the Reviewing Pane open. This heavy pagination overhead often causes Word to freeze.
Open your problematic document in Word for Mac and navigate to the 'View' tab located on the top ribbon.
Click on 'Draft' to change the document view mode. This simplifies the layout and hides the margin balloons.
With the document in Draft view, try selecting and editing your comments or tracked changes again to see if the performance has improved.

Test the Content in a New Blank Document
Transferring your content to a new file helps determine if the freezing issue is caused by document corruption rather than Word's default behavior.

Frequently Asked Questions
Why does the Reviewing Pane open automatically in Word for Mac?
Word automatically opens the Reviewing Pane when you are in Page Layout view and the document contains too many lengthy comments. When comment balloons cannot physically fit within the page margins, Word uses the Reviewing Pane to display them, as it is not restricted by page boundaries.
Can I completely disable the automatic Reviewing Pane in Word?
You cannot strictly disable this automatic switch if the comment balloons overflow the physical page limits in Print Layout view. To prevent the pane from popping up automatically, you must either switch to Draft view or resolve/delete enough comments so they fit in the margins.
Why does my Word document freeze specifically when I click a comment?
Documents with extensive formatting, heavy tracked changes, and numerous long comments require significant processing power to paginate. Clicking a comment forces Word to calculate where the balloon should appear on the screen, which can cause high display overhead and lead to freezing on larger files.
