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:


I have `transient-mark-mode t'

When I right click into a buffer that creates an active region.
If I now scroll down and right click again, the active region is
extended as expected.

If I keep on scrolling and right-clicking, so that the start of the
regions scrolls off the window, the region is truncated and now starts
on the first visible line.

Not sure, if this behaviour is expected, but it's different from what
emacs22 did.

Also, this is very surprising, since pasting the region into another
bufer through middle-click, does not paste what I expected. Thus messing
up the target buffer and causing data loss that way.




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'.
If you would like to further debug the crash, please read the file
/usr/local/share/emacs/23.0.92/etc/DEBUG for instructions.

I can't reproduce this.  Did you scroll using the mouse-wheel, the
scroll-bar, or some other method?  Please provide a *precise* set of
instructions for reproducing this bug, starting from emacs -Q.

When point moves due to scrolling, the mark is deactivated---at least,
that's what I observe.  This does not move the mark; it remains at the
same position as before, just deactivated.  You can verify this with C-x
C-x.

So I don't see any bug here.
