is this every time you change messages? Do you have any extensions installed?
I'm not seeing this behavior.

Yes, it happens every time.
I've tested with fresh profile - it makes no difference. Bug still present with
fresh profile.

Also I'm going to test tomorrow on my work with Windows 2000 machine.

I've tested builds on Windows 2000 SP4 and I don't see this bug.

I tried almost everything possible with my home Windows XP machine (remove and
reinstall drivers, shut down all services and programs, install Windows XP SP2)
- no effect. Bug still present.

Also I've tested Mozilla Mail latest trunk - bug doesn't present, so it looks
like Thunderbird only.

I'll try to reinstall Windows XP from scratch on week-end. May be it helps.
