I upgraded to Windows 10 from Windows 8.1. Everything works fine except for a Windows Store app called iBird Pro. When I first booted into Windows, the shortcut to the app was removed from my Applications (Parallels) folder. I copied it back to the folder from a backup and dragged the shortcut to my Mac's Dock. The app runs fine in Full Screen or Modality, but it won't launch from the Dock icon when Windows is in Coherence mode. When I restart Windows, the shortcut is once again removed from the Applications (Parallels) folder and the Dock icon displays as a Question Mark. The app worked fine in Coherence mode on Windows 8.1.
