Yes, just open the View pull-down menu and re-check the Connections option.

Since they're trying to perfect the Leaf/Ultrapeer technology, they changed the default view so that it hides the seemingly empty connection list. I'm hoping that they'll modify the protocol so that the Ultrapeer reports it's Horizon size (e.g. 1000 hosts) to Leafs rather than it's traditional 0.4-type connections (e.g. 4 hosts).
