Performer assumes that you do not have the multi-keyboard option. So it
is trying to connect to :0.1 and :0.2.

Try adding a line to set the pipe connections string. The function to
note is setWSConnectionName. It specifies the window server to connect
to.

The following code works in the C++ version.

for (loop=0; loop < max; loop++)
    {
        char str[PF_MAXSTRING];
        char pipeStr[PF_MAXSTRING];
         
        pipe[loop] = pfGetPipe(loop);

        // START HERE

        sprintf(pipeStr, ":%d.0", loop); // TKO
        //sprintf(pipeStr, ":0.%d", loop); // SKO
         
        pfNotify(PFNFY_ALWAYS, PFNFY_PRINT, pipeStr);
        pipe[loop]->setWSConnectionName(pipeStr);
        pipe[loop]->setScreen(loop);
     
        // END HERE

               pfPipeWindow *pw = new pfPipeWindow(pipe[loop]);
        sprintf(str, "IRIS Performer - Pipe %d", loop);
        pw->setName(str);
        if (NumScreens > 1)
        {
            pw->setOriginSize(0, 0, 300, 300);
        } else
            pw->setOriginSize((loop&0x1)*315, ((loop&0x2)>>1)*340, 300, 300);
         
        pw->setConfigFunc(OpenPipeWin);
        pw->config();
    }

Hope this help.
