Ensure that Word, Excel, PowerPoint, and Outlook are completely closed before starting the repair process.

Frequently Asked Questions

Why do my pen highlights move or change shape in Word?

This is a known rendering issue in Microsoft Word where ink annotations from the Draw tab lose their exact anchor coordinates. When the document is saved and reopened, Word misinterprets the data, causing the ink to distort into squiggly lines.

Can I recover the original shape of the distorted ink highlights?

Unfortunately, there is no reliable way to revert the distorted squiggly lines back to their original highlighted state once the file has been saved and closed. They must be manually deleted and recreated.

Is there a safer way to highlight text in Word?

Yes, instead of using the Draw tab, use the Text Highlight Color tool located on the Home tab. This applies color directly to the text background rather than acting as an overlapping vector graphic, ensuring the formatting never distorts.
