Comment 14 for bug 320057

The behaviour was always here.
I have used the same account for years now and I migrate my account directory from computer to computer.
Before I was under Ubuntu 5.10 to 7.04, then I had to migrate under Windows 2003 Server R2, now I am under Vista64.
If I remember correctly when I migrated from 2003 to vista this issue disappeared some weeks/months, it's now back.

I am in the process of searching an other Mail client, it's too boring...

Here is a sample network process
172.16.0.20 is the LDAP server
172.16.0.121 is my workstation
Thunderbird freeze between packets 12 and 13 regardless of the number of matches found.
