Posting this at the request of Michael with ConnectWise Control support:
When using Start Menu or Ctrl-Alt-Del menu to log off of guest machine while host is attached, host session freezes for 60 to 180 seconds.
Guest machine display sometimes shows message "1 program still needs to close: (Waiting for) ShuttingDown". At other times the local display returns immediately to login screen during this period, at which point the local guest user can log back onto the guest machine, while the host session remains frozen for a while. It does not matter whether the host or local guest user initiates the log off.
Issuing the DOS command "logoff console /v" from a DOS window on the guest or from the Commands window in ScreenConnect Access causes the logoff to occur and control to be available from the host session immediately (within the usual log off time).
This has been observed on Windows 7 and Windows 10 guests, under ConnectWise Control releases 6.9 up to 6.9.21415.6941.
