Not for me.

Example?

Your computer locks up until TB finishes? Which version of Windows?
Which version of TB?

Win 7 Pro all updates
TB latest version

PC = Intel Quad 3GHz 8GRAM, 500MB free C:

It is because I have so many eMails with 150K attachements that are
downloading.

TB programmers need to release more code time to the system (allowing TB
to multitask) during such downloads. Maybe TB only uses a few threads??


It's the kind of tool, where some user tuning may be
required. The server has a maximum number of connections,
and the client can be set to use less than that. And if you
set the connections low enough, a more efficient serialization
may occur for you. The latest TB versions are too asynchronous,
and shoot themselves in the foot.

These can be found in the Configuration Editor. In Firefox,
this would be about:config, but in Thunderbird, there is a
button to click to open the Editor. This is like a Registry,
but uses a separate file.
