Yes because they see the working mutex of the first instance and so try to connect to the TCP port instead of opening a new one. I added one more debug message for exact this case in https://github.com/geany/geany/pull/2111/commits/ec10be0ddf6bc1a4f7c144de489cd553ccf7f161. The real problem remains in the failed bind of the first instance. > Is 127.0.0.1:49876: 10013 changeable anywhere? Or is hard-coded It's hard-coded since it usually doesn't cause any problems. Even if, changing the port number probably won't solve your problem. > Other lead is cygwin installation, maybe it has done some havoc. Are there > any complains using stand-alone geany and cygwin?
