Subject: 23.1; frame switching -vs- input buffering
Date: Thu, 20 Aug 2009 14:58:45 -0600

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 bug-gnu-emacs <at> gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:


My standard Emacs setup has two frames side-by-side.
I often switch between the frames using `other-frame'.

If I am typing quickly, and type the binding for other-frame
(here C-z o, but C-x 5 n should work as well) followed immediately by
other text, the subsequent text will often go to the previous frame.

I expect other-frame to be synchronous in its operation with respect to
other typing I do afterward.  Currently I have to pause after
other-frame, to let Emacs "catch up" and move its focus to the other
frame before resuming.



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/share/emacs/23.1/etc/DEBUG for instructions.

I'm unable to reproduce this in Emacs 24.  Do you still see this bug in
a current Emacs?

More information was requested, but was apparently not given, so I'm
closing this bug report.  If this is still a problem, please reopen this

Sorry, I was away for quite a while.

I can't say I have noticed it on 24, but I will keep looking.
Try it on a machine under load.
