stwert, if you were using a mac you could just change it without having to use hacks :p
i downloaded something called display fusion, it's free (the paid one has more features though)
i too usually have renders as my backgrounds but a few weeks ago i changed it to other pictures after installing windows 7
probably can't see it but those folders and documents on my desktop are all labeled untitled something... because i usually just put tempory thigns onto the desktop or things i dont know where to put onto the desktop
that's a "Ch" pronounced as a "K"
Computer skills I should have:
Maya, XSI, Photoshop, AfterEffects, Motion, Illustrator, Flash, Swift3D
