Actually that's not what I'm experiencing. The only effect of clicking on an unread folder entry is to
just clear that entry. It also decreases Thunderbird's unread badge icon in
the Unity launcher, from the same number of messages the entry accounted for. This all makes perfect
sense, the only missing part is focusing Thunderbird when it's on another workspace (which is, I believe,
a pretty common setup)
