Embedding form in Sharepoint

We have a simple one question form I embedded into a Sharepoint online page.  It seems to work for the few others I tested except the creator of the form.  He sees the following screen and clicking the Fill out the form link opens in a new window for him.  The embed code points to the responsepage.aspx.  Any idea why it won't display the form in frame for him?  Multiple browsers do the same thing for him.
