I got so fed up with trying to get a decent transparent edge on the piece that I was working on that I decided.. FI! I'll do something rectangular... wrong!
Don't know why but Coolplayer refused to load these ini files until I rewrote the slider information in a format that is so alien to everything else that I have previously used ( that works ??? ) that I began to wonder if I was coming or going.
Anyway, got there, and although it's kinda plain I quite like it
