LW"s menu bar, View -> Show / Hide Connections

Is not clickable did you mean. um ... sounds like a java issue. Make sure LW is fully loaded & settled before you try to connect. If you have a lot of incomplete & shared files then LW can be slow responding whilst it is loading.

If it is not connecting, try going to Tools > Options > Advanced > Performance & disabling DHT & ultrapeer capabilities. Then go to File menu, Choose Disconnect. Wait 5 mins, choose Connect again.
