V4.3 qubes.Filecopy broken, Request refused everywhere

Changes:

  • Same session, no updates in between works and broken.
  • Changed policy for mouse input in timeframe via Global Settings menu (because after pressing ESC once, while the mouse allow prompt was focused, because something grabbed the keyboard and I couldn’t type, the prompt never showed up again on mouse replug or usbvm restart, I tried setting the policy off and ask again)

Troubleshooting done:

  • Policy daemon in dom0 restarted. No effect.

EDIT: Fixed it.

The XFCE notification system was stuck, therefore the prompt could not appear and the request was refused. Restarting XFCE fixed it. (The guest windows stay open even.)
