Scrolling with rMBP

I purchased this app in June and immediately realized that while optimized for retina display it is unusable. It is not possible to view any content since the application does not (recognize the trackpad?) [Impossible to scroll in any direction]. I was told an update was being prepared in June however its now November and nothing has been updated. This application will not function correctly on a MacBook Pro with Retina Display.
