      I don't think I can run my Qt code in VS, I believe I first need to install the VS plugin for Qt?
      I've never compiled Qt code with VS, I use Qt only with Qt creator.

            can you reproduce this in small sample?
            Might be a bug then.

                There is no upload function here.
                I use dropbox as it very easy to share.

                But if sample very small, its fine to post directly.

                  The IPServer class is initialized from another class:

                  myServer = new IPServer();

                      I have recompiled on another PC with Qt version 5.5.0 (still mvsc2013 compiler) and it works fine; debug, release & deployed.

                        so it seems to be Qt 5.5.1 related ?
                        I dont have VS compiler so cant check here.

                          It could be. Although it was working fine in previous release with Qt 5.5.1.
