Port Map All PnP Mappings close button does not work

[nobulart]

Port Map 2.0.1 (85) OS X 10.11.6 (El Capitan)

To attempt to reproduce this bug: Click on the "All UPnP Mappings" button, then click on the "Close" button. In my case the close button has no effect and I have to forcefully close the app.
