I am experiencing this problem too. As far as I can recall it has only just started in the last few days. Usually when it locks up, the entire system becomes unresponsive for several seconds.
I have tried disabling the LDAP server (a university network, so nearly always on) and it made no difference. This is Thunderbird 2.0.0.23, whatever is in the Ubuntu Jaunty repository, on a 64 bit system. I have a lot of extensions but no new ones in months. -- Thunderbird hangs for 10secs when auto-completing address https://bugs.launchpad.net/bugs/320057 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
