Did you do an upgrade in the past 2 hours or so (it's now 2:35 PM 12/7/09)?
I did an upgrade and a dpkg-reconfigure, and now I lost the top of the main panel (icepanel?), the part that shows the network connection.
The network icon is now on another page and HUGE, takes almost the full page.
Did I do something wrong?
that was a bug that was fixed. The fixed package should be available soon. You can fix it manually by adding SetDockType=true to the trayer launch command in /etc/matchbox/session.
