MS Word keeps randomly pasting from the clipboard when editing a document (on Macbook Pro 2020)

[Evo81]

I'm editing a word document. On a regular basis, the last contents of the clipboard gets pasted into the word document, without me asking it too.

For ages I though I was somehow hitting an incorrect key, but I have typed very very carefully and it still "just happens , sometimes more than a couple of times a minute

Its really annoying!

This is the second Macbook Pro this has happened on. It does not happen with any other applications, which maybe points to it being a problem with MS word?

The MS Office suite is up to date (word version 16.81 24011420)

Restarting your computer may suffice to fix the issue. If it doesn't, consider asking in the Mac category in the Windows Community and/or in an Apple Mac forum.

@Stefan_Blom Thanks, I have posted on some other boards. But its but going on for weeks, past many shutdown cycles and a replacement laptop. I thought it was user error for ages...
