#1453 Windows 10 1803 with VNC 2.8.8 as Service breaks when UAC prompt appears

[John Schultz]

Running Windows 10 ver 1803 computer with TightVNC 2.8.8 as a service. When a "guest" establishes a remote connection it works fine until the UAC admin /password prompt is brougth up. The image of the connection does not refresh. Restarting the service on the "host" and reconnecting from the "guest" fixes the issue and future UAC prompts work fine.
