Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

Despite setting focus-follows-mouse to t using (setq focus-follows-mouse
t) when starting with Emacs -Q, focus does not change when I split the
frame into two windows.  Cursor remains a blank box (no blinking)
despite mouse movement.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
/usr/share/emacs/23.1.50/etc/DEBUG.

`focus-follows-mouse' is a variable you should set corresponding to your
window manager's mouse focus policy.  It affects Emacs frames only.

What you probably want to set is `mouse-autoselect-window'.
