When a connection is rejected by uvnc server (due to the action of Query On Incoming Connection), the previous viewer will return an error message of "Your connection has been rejected".
With the 1.0.8.x or 1.0.9.x, the viewer in this situation will prompt user for input of password, and then return an error of "authentication rejected". This is obvious not correct and misleading.
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
