Hi Tom,

Which window manager are you using?  What do you mean by "not
reachable?"  If Ubuntu Netbook Edition maximizes the Emacs frame, the
ediff-control-panel may end up beneath the active frame.

You can customize this behavior with

M-x customize-group RET ediff-window RET

Look at the variable `ediff-window-setup-function'.  You can customize
it so that everything stays in one frame, which is probably best with
limited screen space.
