Photoshop CS3 Delete key issues...-_-
Simple. I'm assuming that you're only working with the background layer for the first case. If that's the case and there's a lock icon next to the layer, duplicate it (ctrl-j) and delete the original.
The second case is that it inherits opacity from the eraser, change it to 100% and see if that works, sometimes it does that for some odd reason.
If that doesn't help, post again with what exactly happens.
Fill and flow are set to 100% yes, Eraser is set to 100% aswell Im workinging with 2 layers example this is what i experience
Layer 1 (ill draw a circle on it ill select with with lasso and make sure im on layer 1 and press delete.. it sets opacity to 10% i have checked my sticky keys aswell so it cant be those..)
