Blank screen after using FileOpenPicker
I added a key press handler to the default C++ holographic template (the spinning cube example app) that uses the FileOpenPicker. After picking a file or even hitting Cancel, the picker closes but the scene does not return to the spinning cube - it is just a blank screen. Is there something I need to do to return to the scene properly? I've put breakpoints on various handlers to see if deactivation is occuring or something but no luck.
