Does anyone know of a Notepad-like program in which I can set the background to black and the text to white? Preferably, the program should be low in resource usage and should have the basic Notepad functions (eg, search, word wrap, etc.) I am currently using GetDiz but it doesn't render some of the characters well (probably lack of character support or something like that.)

EditPad Pro, my favourite Notepad replacement can do that (and a whole load more)
