IE: “To display the webpage again…” alert pop up?

We are experiencing an issue in IE (11 at least) where when a user submits the password, they are prompted with the following alert:

To display the webpage again, the web browser needs to resend the information you’ve previously submitted.

If you were making a purchase, you should click cancel to avoid a duplicate transaction. otherwise click retry to display the webpage again.

Is there any way to resolve this issue in IE? Our client is the only one experiencing this issue, and “Don’t use IE” is not an option, unfortunately.

Thanks for your time.
