Do you take special steps with the Ediff frame?  That's the

I typically use `ediff-buffers'.  In my setup (non-nil `pop-up-frames' etc.),
each of the two buffers is typically in its own frame; those (portrait) frames
are side by side; and the Ediff Control Panel (buffer `Ediff') is a separate
(tiny) frame.  

You didn't say what kinds of problems you see.

Sorry; I didn't mean to sound like I was reporting a bug as much as an
uncomfortable system interaction.  My primary problem with ediff is
the Ediff Control Panel; I find that I have to manually give it focus
after almost every operation. I was wondering if anyone had worked out
a way around this annoyance on click-to-focus systems like Windows
and MacOSX.
