UltraVNC 1.6.1.0 - Feedbacks

[counselour]

I just updated from 1.4.6 to 1.6.1.
I ssh tunnel to a vncserver at work (TigerVNC) which works just fine with 1.4.6, but it does not with 1.6.1. I get the following error when I attempt to connect:
Handshake aborted. The context has expired and can no longer be used (0x90317)

Does this mean the TigerVNC server is too old?

remove dev : Will do, just spending all my time on tracing bug reports

It wasn't about the word, it was about how to know if it's stable or not. I thought maybe it was accidentally the old file from the dev version.

Thanks for fixing! BTW, it's still like that in v1.6.0.0

@Rudi De Vos has created a 1.6.3.0-dev build, please test it:

Is there a way with the current MSI-Install file to disable the Desktop Icons during the install?

Why can't ultravnc 1.6.1.0 set preset password with syntax password="" when running silent .msi file?

@Rudi De Vos: The QuerySetting no longer works as it did until 1.4.3.6.
We have tested QuerySetting 2 and 4 in combination with Authost.

4 works according to the following scheme:
+:"accept"; ?:"query"; -:"reject"
Up to version 1.4.3.6 it worked as follows according to the documentation:
4="+:Query, ?:Reject, -:Reject”

2 works according to the following scheme:
+:"accept": ?:"reject"; -:"reject"
Up to version 1.4.3.6 it worked as follows according to the documentation:
2="+:Accept, ?:Query, -:Reject [Default]”

Is there a current documentation or is this a bug?

I'm very sorry, but i don't understand few moments:
1 - how i can disable in silence mode language selecting dialod window? (if I install msi on remote host by cmd i can't do that, because installation is stucking!)
2 - I using (for 1.4.x version) /qn /NORESTART SERVERVIEWER=3 SERVICE=1 PASSWORD="1234" - this silent cmd parameters. How I can now do this?

Thanks!
