I've been working on this site and everything's going great, but all of a sudden the blending options doesn't work anymore.
if I open a new doc and try like a shadow, it'll work. but NO blending options will work in this doc. I don't know if I checked something or unchecked or what but i'm lost, I've spent the last 2 days trying to figure it out and nothing.
here's a pic showing it.
this is the doc in question, everything is hidden except for this experimental green box. as you can see in pic, if I check the color overlay, nothing happens. it's the default option, red and 100% opacity.
is the file corupt or something? did I do this? I have no idea?
does anyone else have an idea?
