Hello, when I try to write code and I reach the column 72, the code starts to get a black background: 
You have `Menu->Edit->Preferences->Editor->Display->Long Line Marker` enabled and set to `background` but the colour scheme yo are using has chosen a bad colour for the background.
Either disable the marker or set it to `Line` or fiddle with the colour scheme (personally I just use `Line` :)
