Santiago and Roberto, I have started a bug report for this issue relating to the xfce-panel here:
https://bugs.launchpad.net/ubuntu/+source/xfce4-panel/+bug/1192688 I also have been having similar problems in Xubuntu 12.04, 12.10, 13.04, 13.10. Pressing ALT+TAB does bring Matlab and other java windows back onto the panel but this is very annoying especially when you are using several different windows. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to libwnck in Ubuntu. https://bugs.launchpad.net/bugs/144406 Title: some windows do not appear in the window list To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/144406/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
