- Scenario
- Adding table or figure captions to a long document containing multiple elements.
- Observed behavior
- Word 2016 becomes unresponsive, freezes, or the caption dialog behaves erratically by moving unexpectedly or selecting the document text.

Isolate the Issue Using a Sample Document
Determine if the freezing is specific to one corrupted file or a general issue with long documents by testing a stripped-down version.
Large documents with complex formatting can sometimes develop file-specific corruption. Testing with a clean, sample document helps isolate whether the problem lies with Word 2016 itself or the specific file.
Open your file explorer, right-click the problematic document, and select 'Copy', then 'Paste' to create a duplicate file for testing.
Open the duplicate document in Word 2016 and delete sensitive text and unnecessary pages, leaving only a few sample tables and figures.
Right-click a table in this sample document and select 'Insert Caption' to see if Word 2016 still freezes during the process.

Frequently Asked Questions
Why does Word 2016 struggle with long documents?
Long documents containing numerous high-resolution figures, complex tables, and extensive cross-references consume significant system memory. This heavy rendering load can cause Word 2016 to become unresponsive or freeze during edits.
How can I prevent freezing when adding captions to heavy files?
You can try breaking your lengthy document into smaller, separate files (such as by chapter) or switch to the 'Draft' view from the View tab before adding captions. This reduces the immediate rendering load on your system.
Does this caption freezing issue affect newer versions of Microsoft Word?
While Word 2016 is particularly known for this specific caption dialog glitch, performance issues with extremely large documents can occasionally affect any version. Keeping your software updated to the newest release generally resolves known bugs.
