I honestly have the same issue. And yet... for some reason, it fixes itself when I pull it up again (I use Gimp) and rename it something. Oh, you don't like the name "test", eh? Well let's see if you work when I name you "GelatinousCubes"! And I swear, it has fixed my problem every single time. Even after I do everything right the first time. Does that actually work with anyone else? Or is my computer vying to take over the internet and already using its' mind control skills on me?
