Thank you both for the feedback.
hmakhlouf , Thanks for the workaround suggestion, I normally initiate the restart, then close the undocked window, then I will initiate a new undocked session a few minutes later, saves me the ste of having to dock it.
Jamony , I tried recreating the file and the reset, still get the same issue. I can live with my workaround, but I do hope Microsoft will eventually fix.
