RFBServer on Pier2

Hi, I'm getting trouble to connect to a remote image using RealVNC. I get a "Connection time out" error message. The configuration is: - PharoCore1.0rc1 (Latest update: #10505) + Seaside 3 + Pier 2 + RFB-lr.13 from <http://source.lukas-renggli.ch/unsorted/>http://source.lukas-renggli.ch/unsorted/, I successfully launch RFBServer thanks to Seaside VNC Controller, and Pier continues serving in spite of that connection failure. However, I tried to connect to a local image using "localhost:0", but I get "Unknown rect encoding". If I ask RealVNC to retry connecting, my image freezes. Its the same after upgrading to *RFB-DamienCassou.28*. I'd greatly appreciate any feedback on this issue. Thank you in advance, Regards, Reza
