I tested about 2 hours and encountered many problems. At first, some general things: (1) If the user starts the debugger, do we really want that the Backtrace buffer pops up in some other frame only because it was displayed there in some window before? (2) A problem with this approach: if the Backtrace buffer was already visible in several windows, it still hops around, because the window `display-buffer-in-window-previously-showing-it' returns is not unique. Now to my tests in detail: - When I start debugging with a 3-windowed frame, and this is the first time at all that I use the debugger at all, even then, the debugger hops around. This has to do with (1), but I don't know why it hops the first time. But it gets much worse. Do the following: - emacs -Q - require 'debug, and load your patch - M-x debug-on-entry dired RET - C-x d RET - hit d three times -> Emacs crashs! This is reproducible here. I use GNU Emacs 24.0.93.1 (i486-pc-linux-gnu, GTK+ Version 3.2.3)\n of 2012-02-16 on zelenka, modified by Debian, btw. This is all a horror to debug. Tell me if I can help with something. Michael
