Use the attached file, starting Emacs, as before, this way, where the first load file is your latest window.el: runemacs.exe -Q --debug-init -l "window-2011-06-21a-MARTIN.el" -l "throw-three.el" -f "1on1-emacs" Then, as before (but no need to exit to top level before typing more chars): M-x f TAB o When you hit TAB, *Completions* is shown in its frame, as expected. As soon as you hit the second char (`o'), you get the read-only error. Note: In the file, both of these two lines are necessary, to cause the error: (add-hook 'post-command-hook '1on1-fit-minibuffer-frame) (setq w32-grab-focus-on-raise nil) The second is of course Windows-specific. If I comment that out then the error is not raised, but instead when I hit `o' the focus just changes to the minibuffer (no `o' char appears in the minibuffer at this point). I can tell that the focus changes because the frame border shows that (the active frame border is a diff color from inactive frame borders - this is a window mgr thing, not an Emacs thing). Then, if I hit `o' a second time it (a single `o' is inserted in the minibuffer. Thx/HTH.
