Hello, I've been trying to get RFB running in Pharo. So, installation was okay, I updated the Configuration to pick the last change from Damien Cassou. Still, I start the server with: RFBServer current initializePreferences; configureForMemoryConservation; allowEmptyPasswords: false; setFullPassword: 'password'; "Clear text passwords..." setViewPassword: 'password'; "... urgh!" enableLogging: true; enableDebugging: true; start: 0. along with RFBLog dumpLogToTranscript: true. Server loads, starts. Now, when I connect with RealVNC, or TightVNC, or OSX built-in VNC, I get a view of the UI (so, a copy of the framebuffer is sent) [image: Inline image 1] The error I get is (as I am in debugging mode): [image: Inline image 2] I followed the contexts upwards in the exception to sendData:startingAt:count: [image: Inline image 3] I wonder why I do not get the VNC client going on as the first screen is sent properly. TIA Phil
