An URL must be selected for this operation

In Hg workbench, clicking push/pull buttons pop out an dialog stating that "An URL must be selected for this operation". The problem is that it leave users no clue about how to select an URL. Trying the settings dialog doesn't help either. This is a really annoying awkward behavior.
