Hello! I and a couple others have experienced this issue as well.

The Unending War >
Speak with Edmelle >

Clicking on Edmelle creates no text-box. Can not progress in-game story because NPC isn't triggering the quest. Can not continue with story. Only indication of right-clicking is that my action bars become greyed-out for a split second before cancelling the action.
