Hi Andreas, I tried this and it didn't work, not with a cygwin window or a regular DOS window. Eventually I'll do some more digging, but for now I'll just use unicast.

If I start the clusterServer's with info log level turned on it seems to work fine don't ask me why need to debug this could be a timing problem? I executed the following in three different cygwin shells on one computer: shell1: export OSG_LOG_LEVEL=info ; ./testClusterServer.exe -w -g320,200,0,0 pipe0 shell2: export OSG_LOG_LEVEL=info ; ./testClusterServer.exe -w -g320,200,320,0 pipe1 shell3: ./testClusterClient.exe -m pipe0 pipe1 > Hi Marcus, > > The -M option triggers creation of a MultiDisplayWindow for the cluster window on the client.
