Text Boxes Have Been Acting Weird Recently

Take this:

- Copy Content to a New Document
Try copying everything except the text boxes into a fresh Word document. Then recreate the text boxes manually. See if the issue persists.
- Disable Hardware Graphics Acceleration
Go to File > Options > Advanced > Display and check “Disable hardware graphics acceleration.” Restart Word and test again.
- Start Word in Safe Mode
Run Word with no add-ins by holding Ctrl while launching it, or run winword /safe from the Run dialog. If the issue disappears, an add-in is likely the culprit.
- Check for Updates
Make sure Office is fully updated. Sometimes these odd behaviors are patched quietly in updates.
- Inspect the Document with Open XML SDK Productivity Tool
If you're comfortable with technical tools, this can help identify hidden links or corruption in the document structure.
