Deselect issue after it's been select

Hey,

I'm having problems trying to deselect an issue/task after it has been selected in the agile board. In the UI it will get a dashed blue border around it when this occurs. If I can't deselect it then the next issue that I go to add via the agile board becomes a child of the selected issue, which is not what I want. I also tried looking for a while to maybe select a swim lane (because I'd like the task to become a child of that), but I can find no way to do this either. Thanks for any insight you can provide!
