[gentoo-user] Thunderbird oddity

[Wols Lists]

It's actually been like this a while - but my Thunderbird has lost its 
title bar. The top bars are the search bar, with the menu bar underneath 
it. So I have an "X" to close thunderbird with on the search bar, but 
that's it. The "v" and "^" to maximise and minimise aren't there because 
the bar they live on isn't there.

How do I get my bar back? -)
(The bar is quite happily on the window I'm typing this email in, just 
not on my main Thunderbird window.)

Cheers,
Wol
