Thunderbird sometimes asks me if I want to compact folders when I start it. So I say Yes. It then pauses folder compaction and asks me for passwords to download mail. If I enter passwords, it gives me an error that it cannot download mail because the folder is locked by the compactor. So I have to manually tell it download the mail.
Why can't it just wait until it's finished compacting folders before downloading mail (or even asking me the passwords to download mail)?
