First of all thank you for developing this essential networking tool!
I have been using listening mode (UltraVNC reverse connection) for many months with version 1.6.4.0 on my server with command from a batch file:
START "" "C:\Program Files\UltraVNC\vncviewer.exe" -listen 55500
after updating to 1.7.1.0 the clients can no longer connect... (the firewall/router connections are not changed)
After reverting to 1.6.4.0 version everything works again...
These window appear instead of the remote desktop:


Thanks for any help or suggestion!
