MSPaint. XD Since I pixel a ton but I have a habit of reporting porn violations around deviantART, it's always important to have a window I can switch too in case I leave the computer mid-report. Since I always use my mother's laptop (I'm poor, can't afford my own laptop and my brother is always hogging the home computer <.<), I use the internet in a private session (yay for no browser history!) and open an MSPaint file, so I switch to it just in case. Usually an avatar in the making, always nice cute girly stuff, so it's all good~
