When Basic example B1 is run and the geometry set to rotate, if you then close the window (click on "X" in top RH corner), the window closes, but the application continues to run. To terminate the application, it is necessary to enter <CNTL>-C in the DOS window. IF the geometry is stationary, there is no problem with closing the application. This problem is not associated directly with example B1 since the same behaviour is observed in my application, which is different from the example, but uses Qt, OpenGL in WIN32 mode. Configuration: G4 v10.2 ref 9, Qt v4.8.6 Windows 7 Compiled with MS Visual Studio express 2015 (VS 14] Build using CMake 3.4.3, WITH_GEANT4_UIVIS switched on Win-32 mode Release (not Debug)
I'm having a similar issue - please see Problem 1868.
