UltraVNC x64 v1.2.1.1 not allowing multiple connections

Postby creehanjt » 2016-08-16 15:44

I am experiencing an issue after installing v1.2.1.1 winvnc server is not allowing more than one connection at a time. The second client connection DOES connect to the server PC but the display is black or gray. I do not experience this with v1.2.1.0

I see something mentioned in the install release notes about this but I am unclear as to whether this means the issue was fixed or is some type of new feature?

This should not happen, the bug fixed was for a single session.
The cause of that bug was the encoder switching before proper initialization.

We tested the server with a script that start 10 connections and kills every minute. Looks like we missed something or it's caused
by some special setting on your site.

*Can you test with a fixed encoder ( viewer option) instead of auto.
*Does your viewer has the same color depth
Anything particular that can help repeating it.
