r75390 gcc dbg crashes reproducibly with BSOD due to unhandled exception thrown from within WIN32SS/gdi when trying to establish a local-loopback connection with the tool "UltraVNC 18.104.22.168".
Just use the viewer to connect to localhost after starting the server.
In earlier ros versions like 0.4.4 I could do this without any issue and it worked.
The tool can be found in rapps.
Keep in mind that MFC42u.dll / MFC42.dll must be placed in system32 to run the tools setup.
