[Windows] XD does not launch immediately after quitting (G13732)
You’ve made a mistake and hit that big red X in the corner of the XD application, but launching it again doesn’t immediately bring up the application. In fact, repeatedly doing so will give you an error message! Instead, you should go make an espresso and wait for XD to launch (it will, we promise!).
This has been fixed in the May 2017 release.
