Flare 2021 r2 - PDF Preview opens in Modal window

[Anita Burstein]

Hi
In Flare 2020 I learned to disable Adobe in IE and then my PDF previews opened in the Adobe window, and not in the Flare modal popup preview window.
I just upgraded to Flare 2021 r2 and now my PDF previews are opening again in the modal window. Any ideas?
Thanks,
Anita
