For me, *Backtrace* is a special-display buffer, so it is shown in its own, special-display frame. In this build, things are not broken (still OK): In GNU Emacs 24.2.50.1 (i386-mingw-nt5.1.2600) of 2012-09-02 on MARVIN Bzr revision: 109861 eggert@cs.ucla.edu-20120902171035-7mzihil3xd6bjfiy Windowing system distributor `Microsoft Corp.', version 5.1.2600 Configured using: `configure --with-gcc (4.6) --no-opt --enable-checking --cflags -ID:/devel/emacs/libs/libXpm-3.5.8/include -ID:/devel/emacs/libs/libXpm-3.5.8/src -ID:/devel/emacs/libs/libpng-dev_1.4.3-1/include -ID:/devel/emacs/libs/zlib-dev_1.2.5-2/include -ID:/devel/emacs/libs/giflib-4.1.4-1/include -ID:/devel/emacs/libs/jpeg-6b-4/include -ID:/devel/emacs/libs/tiff-3.8.2-1/include -ID:/devel/emacs/libs/gnutls-3.0.9/include -ID:/devel/emacs/libs/libiconv-1.13.1-1-dev/include -ID:/devel/emacs/libs/libxml2-2.7.8/include/libxml2' And in this build, things are broken: In GNU Emacs 24.2.50.1 (i386-mingw-nt5.1.2600) of 2012-09-17 on MARVIN Bzr revision: 110062 cyd@gnu.org-20120917054104-r93rtwkrtva73ewe Windowing system distributor `Microsoft Corp.', version 5.1.2600 Configured using: `configure --with-gcc (4.7) --no-opt --enable-checking --cflags -ID:/devel/emacs/libs/libXpm-3.5.8/include -ID:/devel/emacs/libs/libXpm-3.5.8/src -ID:/devel/emacs/libs/libpng-dev_1.4.3-1/include -ID:/devel/emacs/libs/zlib-dev_1.2.5-2/include -ID:/devel/emacs/libs/giflib-4.1.4-1/include -ID:/devel/emacs/libs/jpeg-6b-4/include -ID:/devel/emacs/libs/tiff-3.8.2-1/include -ID:/devel/emacs/libs/gnutls-3.0.9/include -ID:/devel/emacs/libs/libiconv-1.13.1-1-dev/include -ID:/devel/emacs/libs/libxml2-2.7.8/include/libxml2' What is broken is this: Before, the same frame (seemingly) existed throughout. I could hit `d' any number of times, and everything was smooth. I could expand the frame size or reposition it, and it stayed wherever I put it. Now, it appears that each time I hit `d' the frame is deleted and a new frame is created to replace it. And it is always re-created with the same, default size and position (top left of screen). This is horrible. Not only does the re-creation produce a tremendous blink/flash, but the repositioning and resizing back to the default position and size are intolerable. I cannot see anything useful in the buffer - I need to stretch the frame out again after each `d' to see anything wide. And I need to reposition the frame to the right (for example) after each `d', if I have another frame at the left that I want to continue to see (e.g. a frame showing the source code, or *Completions*). If you prefer this as a separate bug report, feel free to copy the above into a new bug - you have all of the info. This is with my own setup, which Martin is pretty familiar with: non-nil popup-frames etc. For me, this change is a horrible regression - makes the debugger unusable.
