Public bug reported: Install OpenOffice.org. Open three OoO Writer windows. Move the mouse to the task list in the panel. Right-click the task-list entry for one OoO window and click `Close Window'. Do the same for a second OoO window. The third OoO window and any other open windows remain responsive, but the entire panel becomes unresponsive. The only way to regain full control is to press Ctrl+Alt+F1, log in, and run `sudo /etc/init.d/lxdm restart'.
The same lock-up occurred once when I opened six or eight OoO windows and held down Alt+F4 long enough for it to auto-repeat, so that all the OoO windows closed quickly. I was left with an unresponsive panel whose task list showed two or three (non-existent) windows. One wrinkle (probably not relevant): I'm running Lubuntu inside VMWare Player 4.01 on top of 32-bit Kubuntu 9.10. The following command output (requested by Launchpad) was taken inside the VM running Lubuntu. msl@lub1110:~$ lsb_release -rd Description: Ubuntu 11.10 Release: 11.10 msl@lub1110:~$ apt-cache policy lxpanel lxpanel: Installed: 0.5.8-1ubuntu3 Candidate: 0.5.8-1ubuntu3 Version table: *** 0.5.8-1ubuntu3 0 500 http://gb.archive.ubuntu.com/ubuntu/ oneiric/universe i386 Packages 100 /var/lib/dpkg/status msl@lub1110:~$ Let me take this opportunity to thank you for the hard work you put into producing Lubuntu.
