Send Ctl Alt Del no effect to login

Postby diezwei » 2020-12-23 10:28

Hello,
no effect by klick on the button send Ctl Alt Del to login on Windows. This ist only on clients with a new Windows installation.
Some clients works fine.
We are using Windows 10 1909 and Ultravnc 1.2.50. This problem was also with version 1.2.23.

Is there a solution to fix this?
