This is codeblocks in debug mode for multiple windows project.

My system has laptop and second monitor connected with hdmi cable.
I use lazy foo examples with Codeblocks.

mingw32-g++.exe -LC:\SDL2-2.0.12\i686-w64-mingw32\lib -LC:\SDL-1.2.15\lib -o bin\Debug\37_multiple_displays.exe obj\Debug\37_multiple_displays.o  -lmingw32 -lSDL2main -lSDL2 -lopengl32 -lglu32 -lgdi32 -mwindows -lglew32mx -lglew32 -lfreetype -lDevIL -lILU -lILUT -lmingw32 -lSDLmain -lSDL -lSDL_image -lsdlgfx -lSDL_mixer -lSDL_ttf -lpthread  
Output file is bin\Debug\37_multiple_displays.exe with size 1.00 MB

Both examples fail same way when i move window to the second display.
