Yes this is right. I could get a picture of the stuck Emacs (attached)

Description: PNG image

it does not get the focus of MSW, I could have the picture only by
iconizing all the other apps, so that the stuck Emacs gets visible. As
you see I was running an `M-x diff-revision' on the stuck Emacs when it
happened.

Please let me know, and then I can close it.
