Problem with switching LibeOffice windows by Alt+Tab and in vertical panel

Issue is open for this problem: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/844119
Please vote to raise importance of this bug.

Workaround suggested Matthias Niess in bug comments:

switching works fine if open SpreadSheet from Dash and then open files from Cntl+O.

as an option you can install LibreOffice4 from official site - but in this case you loose Unity integration of menu, (instructions for installation).

update:
looks like fixed in latest ubuntu updates (March 2013), I aslo updated Libreoffice to 4.0 by http://www.webupd8.org/2013/03/install-libreoffice-40-in-ubuntu-1204.html

sudo add-apt-repository ppa:libreoffice/libreoffice-4-0
sudo apt-get update

.... and do install from ubuntu Center, and now Libreoffice works fine.
