Browse Open Documents not showing thumbnail previews?

Hi there,

I've written a macro that saves bodies of a part into seperate files. However, after running, the Browse Open Documents pane does not show thumbnails. Is there anything I can do, maybe at the end of the macro, to create these preview thumbnails. I am saving each body, I tried rebuilding, and I tried reactivating each file in turn, but nothing worked and I'm not sure how these are created.

Current appearance after macro is run:

Desired appearance after macro is run:

Thanks.
