UPDATE: I compiled and updated lxpanel to 0.5.8 in my box and the issue has been fixed. Or at least I couldn't reproduce it anymore.
I had to install libgtk2.0-dev, libmenu-cache1-dev and intltool packages in order to compile it, but it was worth the hassle. For those affected by this: *Install the following packages sudo apt-get install libgtk2.0-dev libmenu-cache1-dev intltool Download lxpanel source from http://sourceforge.net/projects/lxde/files/LXPanel%20%28desktop%20panel%29/ Compile it and install it: ./configure --prefix=/usr make sudo make install Log out and log in again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/800297 Title: lxpanel freezes when many programs are open and lxpanel is being used To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxpanel/+bug/800297/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
