Microsoft Word clears clipboard data when it closes

Question

When I copy information from a document (just some text) out of Microsoft Word, then close the document and re-open it, the clipboard data is gone.

What is happening here, and how can I stop Microsoft Word from messing with my clipboard data?

---

Steps to Reproduce:

• With an existing Word document, mark it as Read-only on Windows.
• Open Word.
• Make a modification. Copy some text.
• Attempt to save. The "Save As..." dialog appears because the file is read-only.
• Do not save. Press Cancel instead.
• Close Word.
• Mark the file as not Read-only.
• Open the document again.
• Try to paste.

When you try to paste, nothing happens, the clipboard was cleared.

Per Microsoft,the clipboard data is not cleared. I know you do get a prompt if you have large amounts of data in the clipboard, but I do not know of a way to automatically clear the clipboard on exit.

My guess is this is a third party program.

Or perhaps you can provide a specific example.
