RE: Optiplex 9010 AIO Screen goes black and freezes on logout.
Reinstalled v 188.8.131.52. Crashed after 4 logoffs.
Uninstalled v184.108.40.206. Rebooted. Installed v 220.127.116.11 (note: running the 18.104.22.168 .exe over an existing 22.214.171.124 install will NOT update the application).
I've had 50+ successful logon/logoff's since updating to v 126.96.36.199.
This appears to have solved our issue with 9010's locking up at logoff: Remove DellOSD v 188.8.131.52. Install 184.108.40.206 (or don't use DellOSD on the Optiplex 9010 AIO period).
hope it fixes your issue also.
