Workaround I use:
after starting ediff-buffers, or ediff-files, for example:
1) ctrl-alt-num pad 5 -- this maximizes the small ediff window to whole screen; it contains text 'type ? for help'
2) type ? -- this brings up the help text; this window still fills up whole screen
3) type ? -- this minimizes ediff window; on my system, this little ediff window is not visible at all now
4) proceed w/ ediff session -- ediff responds as though commands were typed into little ediff window even though it is not visible. Typing ? again brings up help text in a window that fills whole screen, then type ? again to make it go away.
*Note* if, in the middle of ediff session, user switches to different window, by using alt-tab for instance, then comes back to emacs, the focus will no longer be in the small ediff window, but in the emacs frame itself.
Using:
GNU Emacs 23.3.1 (i686-pc-linux-gnu, GTK+ Version 2.24.10)
Ubuntu 12.04 LTS
unity 5.18.0-0ubuntu2
