As I was... think FIREWALL - the one on your PC! If you're getting connection time-outs when using iTest VNC, but not when using a native VNC viewer, examine your PC's firewall rules. It's very likely that the iTest program and its traffic is being blocked. In Windows 7, set two inbound rules: one rule for TCP and one for UDP. Allow any locol/remote address, protocol, port, computer or user access to iTest - and be sure to apply these rules on all profiles (domain, private, public, etc...). Also, currently the VNC session requires encryption to be set to "always off" or "preferred off" and authentication to be set to either "none" or VNC password". Best of luck...
