Wrong key code sent

Line 447: return keys[shift ? 2 : 1];

Should be
return keys[shift ? 1 : 0];

Screen does not update

I checked out the source code and run without any modifications.
I connected to a VNC server successfully, but when I move or click the mouse or type something with the keyboard, the screen is not updated. I tried to put "console.trace()" into server.js #handleFrame() function and found out that it was never called more than once in the whole 15 minutes.

Note: I connect to a real VNC service on another VM on the same host, so network latency is absolutely out of question.

Server dies on start

▶ time node server.js
Listening on port 8090
node server.js  0.20s user 0.04s system 99% cpu 0.239 total

as you can see, the server stops right after Listening on port 8090. No errors are present. Any idea what's happening?

TypeError on npm Start

It needs to be rfb2
var RFB = require('rfb2');

After making the changes, npm start throws an error:
`Listening on port 8090
