Hello,
we use UVNC SC (Listening Mode...)
with the newest version, we have the Problem, that after the connection is closed, the administrated system sometimes gets blocked, so that the user cannot do anything anymore.
We switched back to earlier versions and there everything is fine.
I don't know when this happens exactly, but it does! This seems to be a bug and it would be great if you could fix it.
After more 2 000 000 (two million) views on forum for 1.5.0.x development versions... and 1.6.1.0, 1.6.3.0-dev versions
A new stable version, UltraVNC 1.6.4.0 and UltraVNC SC 1.6.4.0 have been released: https://forum.uvnc.com/viewtopic.php?t=38095
Feedback is always welcome

Re: System blocked after quit Connection
