[jitsi-users] Window manipulation buttons not appearing in title bar of Options window

Hi all,

This is regarding Jitsi nightlies on 32-bit Debian Wheezy, running MATE

i've found that recent nightly builds are not displaying the window
manipulation buttons (minimise, maximise, close) in the title bar of the
Options window. To close the Options window, i have to use Alt-F4. The
relevant buttons are being displayed (and are functioning) just fine in
the main Jitsi window, however.

Is anyone else experiencing this?
