I was making a sig and i brought a render of that was too big and i wanted to see what it would look like if it had a "out of bounds" type of effect. So I click Image>Reveal All and I have Layer 1 (Transparent Layer) showing slighly at the top and bottom and i cleared my history by accident and now it's stuck on Reveal All. I want it to go back to a regular 400x125 sig.
