When I run = ediff-buffers, hit =E2=80=98?=E2=80=99, switch back to the main frame, = and evaluate the elisp you sent, I get =E2=80=99nil=E2=80=99 in the mini = buffer and the buffer *foo* has the help text in it. However, the help = frame is still empty. I=E2=80=99m trying to understand what this means. = It seems like the frame has the right buffer assigned to it but that it = is in some weird mode so that it isn=E2=80=99t being rendered properly.=20= Thanks for the help!
