I'm following some tutorials on youtube for setting up UVs, and I can successfully follow along with texturing a cube. After that I try to make another cube and do the same thing (make primitive, mark seams, unwrap), but when I hit unwrap, the UV/image editor window doesn't get an unwrapped cube like before. If there was an image on it previously (from the last cube), it goes away so I just see the blank gray grid. Anyone have any idea what I might be doing wrong?

I'm on Blender 2.5 BTW.

EDIT: Figured it out. Always select all before unwrapping...
