Ok here's another question:

I don't know what I did, but I'm trying to make another LO and start it as a 8.5x11, (In PSE3), but it won't let me, it's only letting me round it to 9 (instead of 8.5). I know there's something you can deselect to make it so you can do any proportions you want but I forgot what it was. I don't know why it went back to the default for somereason. Ughhhh.
