Using UltraVNC Viewer 1.1.9 with UltraVNC Server 1.2.30
Re: Using UltraVNC Viewer 1.1.9 with UltraVNC Server 1.2.30
For security reasons it's best to upgrade the UltraVNC Viewer to at least 1.2.2.4.

Re: Using UltraVNC Viewer 1.1.9 with UltraVNC Server 1.2.30
Hello
If we update the UltraVNC Viewer to latest version 1.2.30 is it still compatible with the older version of UltraVNC Server 1.1.9?
